Now that the default value for TEST_PASSES_SANITIZE_LEAK is `true` there
is no longer a need to have that variable declared in all of our tests.
Drop it.

The `OPT__ABBREV()` option can be used to add an option that abbreviates
object IDs. When given a length longer than `the_hash_algo->hexsz`, then
it will instead set the length to that maximum length.
It may not always be guaranteed that we have `the_hash_algo` initialized
properly as the hash algorithm can only be set up after we have set up
`the_repository`. In that case, the hash would always be truncated to
the hex length of SHA1, which may not be what the user desires.
In practice it's not a problem as all commands that use `OPT__ABBREV()`
also have `RUN_SETUP` set and thus cannot work without a repository.
Consequently, both `the_repository` and `the_hash_algo` would be
properly set up.
Regardless of that, harden the code to not truncate the length when we
didn't set up a repository.

Giving an argument to an option that doesn't take one causes Git to
report that error specifically:
$ git rm --dry-run=bogus
error: option `dry-run' takes no value
The same is true when the option is negated or abbreviated:
$ git rm --no-dry-run=bogus
error: option `no-dry-run' takes no value
$ git rm --dry=bogus
error: option `dry-run' takes no value
Not so when doing both, though:
$ git rm --no-dry=bogus
error: unknown option `no-dry=bogus'
usage: git rm [-f | --force] [-n] [-r] [--cached] [--ignore-unmatch]
(Rest of the usage message omitted.)
Improve consistency and usefulness of the error message by recognizing
abbreviated negated options even if they have a (most likely bogus)
argument. With this patch we get:
$ git rm --no-dry=bogus
error: option `no-dry-run' takes no value

Continue the work of 12909b6b8a (i18n: turn "options are incompatible"
into "cannot be used together", 2022-01-05) and a699367bb8 (i18n:
factorize more 'incompatible options' messages, 2022-01-31) to use the
same parameterized error message for reporting incompatible command line
options. This reduces the number of strings to translate and makes the
UI slightly more consistent.

Another step to deprecate test_i18ngrep.
* jc/test-i18ngrep:

They are equivalents and the former still exists, so as long as the
only change this commit makes are to rewrite test_i18ngrep to
test_grep, there won't be any new bug, even if there still are
callers of test_i18ngrep remaining in the tree, or when merged to
other topics that add new uses of test_i18ngrep.
This patch was produced more or less with
git grep -l -e 'test_i18ngrep ' 't/t[0-9][0-9][0-9][0-9]-*.sh' |
xargs perl -p -i -e 's/test_i18ngrep /test_grep /'
and a good way to sanity check the result yourself is to run the
above in a checkout of c4603c1c (test framework: further deprecate
test_i18ngrep, 2023-10-31) and compare the resulting working tree
contents with the result of applying this patch to the same commit.
You'll see that test_i18ngrep in a few t/lib-*.sh files corrected,
in addition to the manual reproduction.

Only a single PARSE_OPT_CMDMODE option can be specified for the same
variable at the same time. This is enforced by get_value(), but the
error messages are imprecise in three ways:
1. If a non-PARSE_OPT_CMDMODE option changes the value variable of a
PARSE_OPT_CMDMODE option then an ominously vague message is shown:
$ t/helper/test-tool parse-options --set23 --mode1
error: option `mode1' : incompatible with something else
Worse: If the order of options is reversed then no error is reported at
all:
$ t/helper/test-tool parse-options --mode1 --set23
boolean: 0
integer: 23
magnitude: 0
timestamp: 0
string: (not set)
abbrev: 7
verbose: -1
quiet: 0
dry run: no
file: (not set)
Fortunately this can currently only happen in the test helper; actual
Git commands don't share the same variable for the value of options with
and without the flag PARSE_OPT_CMDMODE.
2. If there are multiple options with the same value (synonyms), then
the one that is defined first is shown rather than the one actually
given on the command line, which is confusing:
$ git am --resolved --quit
error: option `quit' is incompatible with --continue
3. Arguments of PARSE_OPT_CMDMODE options are not handled by the
parse-option machinery. This is left to the callback function. We
currently only have a single affected option, --show-current-patch of
git am. Errors for it can show an argument that was not actually given
on the command line:
$ git am --show-current-patch --show-current-patch=diff
error: options '--show-current-patch=diff' and '--show-current-patch=raw' cannot be used together
The options --show-current-patch and --show-current-patch=raw are
synonyms, but the error accuses the user of input they did not actually
made. Or it can awkwardly print a NULL pointer:
$ git am --show-current-patch=diff --show-current-patch
error: options '--show-current-patch=(null)' and '--show-current-patch=diff' cannot be used together
The reasons for these shortcomings is that the current code checks
incompatibility only when encountering a PARSE_OPT_CMDMODE option at the
command line, and that it searches the previous incompatible option by
value.
Fix the first two points by checking all PARSE_OPT_CMDMODE variables
after parsing each option and by storing all relevant details if their
value changed. Do that whether or not the changing options has the flag
PARSE_OPT_CMDMODE set. Report an incompatibility only if two options
change the variable to different values and at least one of them is a
PARSE_OPT_CMDMODE option. This changes the output of the first three
examples above to:
$ t/helper/test-tool parse-options --set23 --mode1
error: --mode1 is incompatible with --set23
$ t/helper/test-tool parse-options --mode1 --set23
error: --set23 is incompatible with --mode1
$ git am --resolved --quit
error: --quit is incompatible with --resolved
Store the argument of PARSE_OPT_CMDMODE options of type OPTION_CALLBACK
as well to allow taking over the responsibility for compatibility
checking from the callback function. The next patch will use this
capability to fix the messages for git am --show-current-patch.
Use a linked list for storing the PARSE_OPT_CMDMODE variables. This
somewhat outdated data structure is simple and suffices, as the number
of elements per command is currently only zero or one. We do support
multiple different command modes variables per command, but I don't
expect that we'd ever use a significant number of them. Once we do we
can switch to a hashmap.
Since we no longer need to search the conflicting option, the all_opts
parameter of get_value() is no longer used. Remove it.
Extend the tests to check for both conflicting option names, but don't
insist on a particular order.

Avoid showing an optional "no-" for options that already start with a

Add a "[no-]" prefix to options without the flag PARSE_OPT_NONEG to
document the fact that you can negate them.
This looks a bit strange for options that already start with "no-", e.g.
for the option --no-name of git show-branch:
--[no-]no-name suppress naming strings
You can actually use --no-no-name as an alias of --name, so the short
help is not wrong. If we strip off any of the "no-"s, we lose either
the ability to see if the remaining one belongs to the documented
variant or to see if it can be negated.

The parse-options API responds to "git cmd -h" by listing the option
flag (padded to the USAGE_OPTS_WIDTH column), followed by USAGE_GAP
(set to 2) whitespaces, followed by the help text. If the flags
part does not fit within the USAGE_OPTS_WIDTH, the help text is given
on its own line. Imagine that "@" below depicts the USAGE_OPTS_WIDTH'th
column, and "#" are for the usage help text, the output may look
like this:
@@@@@@@@@@@@@ ########################################
-f description of the flag '-f' comes here
--short=<num> description of the flag '--short'
--very-long-option=<number>
description of the flag '--very-long-option'
This is all good and nice in principle, but it becomes awkward when
the flags part is just one column over the limit and forces a line
break. See the description of the "--almost" option below:
@@@@@@@@@@@@@ ########################################
-f description of the flag '-f' comes here
--short=<num> description of the flag '--short'
--almost=<num>
description of the flag '--almost'
--very-long-option=<number>
description of the flag '--very-long-option'
If we allow shrinking the gap to a single whitespace only in such a
case, we would instead get:
@@@@@@@@@@@@@ ########################################
-f description of the flag '-f' comes here
--short=<num> description of the flag '--short'
--almost=<num> description of the flag '--almost'
--very-long-option=<number>
description of the flag '--very-long-option'
and the boundary between the flags and their descriptions does not
become any harder to see, while saving precious vertical screen real
estate.

When "-h" triggers the short-help in a command that implements its
option parsing using the parse-options API, the option help text is
shown with a single fprintf() as a long line. When the text is
multi-line, the second and subsequent lines are not left padded,
that breaks the alignment across options.
Borrowing the idea from the advice API where its hint strings are
shown with (localized) "hint:" prefix, let's internally split the
(localized) help text into lines, and showing the first line, pad
the remaining lines to align.

If the input to strtoimax() or strtoumax() does not contain any digits
then they return zero and set `end` to point to the start of the input
string. git_parse_[un]signed() do not check `end` and so fail to return
an error and instead return a value of zero if the input string is a
valid units factor without any digits (e.g "k").
Tests are added to check that 'git config --int' and OPT_MAGNITUDE()
reject a units specifier without a leading digit.

git_parse_unsigned() relies on strtoumax() which unfortunately parses
negative values as large positive integers. Fix this by rejecting any
string that contains '-' as we do in strtoul_ui(). I've chosen to treat
negative numbers as invalid input and set errno to EINVAL rather than
ERANGE one the basis that they are never acceptable if we're looking for
a unsigned integer. This is also consistent with the existing behavior
of rejecting "1–2" with EINVAL.
As we do not have unit tests for this function it is tested indirectly
by checking that negative values of reject for core.bigFileThreshold are
rejected. As this function is also used by OPT_MAGNITUDE() a test is
added to check that rejects negative values too.

Several Git commands have subcommands to implement mutually exclusive
"operation modes", and they usually parse their subcommand argument
with a bunch of if-else if statements.
Teach parse-options to handle subcommands as well, which will result
in shorter and simpler code with consistent error handling and error
messages on unknown or missing subcommand, and it will also make
possible for our Bash completion script to handle subcommands
programmatically.
The approach is guided by the following observations:
- Most subcommands [1] are implemented in dedicated functions, and
most of those functions [2] either have a signature matching the
'int cmd_foo(int argc, const char **argc, const char *prefix)'
signature of builtin commands or can be trivially converted to
that signature, because they miss only that last prefix parameter
or have no parameters at all.
- Subcommand arguments only have long form, and they have no double
dash prefix, no negated form, and no description, and they don't
take any arguments, and can't be abbreviated.
- There must be exactly one subcommand among the arguments, or zero
if the command has a default operation mode.
- All arguments following the subcommand are considered to be
arguments of the subcommand, and, conversely, arguments meant for
the subcommand may not preceed the subcommand.
So in the end subcommand declaration and parsing would look something
like this:
parse_opt_subcommand_fn *fn = NULL;
struct option builtin_commit_graph_options[] = {
OPT_STRING(0, "object-dir", &opts.obj_dir, N_("dir"),
N_("the object directory to store the graph")),
OPT_SUBCOMMAND("verify", &fn, graph_verify),
OPT_SUBCOMMAND("write", &fn, graph_write),
OPT_END(),
};
argc = parse_options(argc, argv, prefix, options,
builtin_commit_graph_usage, 0);
return fn(argc, argv, prefix);
Here each OPT_SUBCOMMAND specifies the name of the subcommand and the
function implementing it, and the address of the same 'fn' subcommand
function pointer. parse_options() then processes the arguments until
it finds the first argument matching one of the subcommands, sets 'fn'
to the function associated with that subcommand, and returns, leaving
the rest of the arguments unprocessed. If none of the listed
subcommands is found among the arguments, parse_options() will show
usage and abort.
If a command has a default operation mode, 'fn' should be initialized
to the function implementing that mode, and parse_options() should be
invoked with the PARSE_OPT_SUBCOMMAND_OPTIONAL flag. In this case
parse_options() won't error out when not finding any subcommands, but
will return leaving 'fn' unchanged. Note that if that default
operation mode has any --options, then the PARSE_OPT_KEEP_UNKNOWN_OPT
flag is necessary as well (otherwise parse_options() would error out
upon seeing the unknown option meant to the default operation mode).
Some thoughts about the implementation:
- The same pointer to 'fn' must be specified as 'value' for each
OPT_SUBCOMMAND, because there can be only one set of mutually
exclusive subcommands; parse_options() will BUG() otherwise.
There are other ways to tell parse_options() where to put the
function associated with the subcommand given on the command line,
but I didn't like them:
- Change parse_options()'s signature by adding a pointer to
subcommand function to be set to the function associated with
the given subcommand, affecting all callsites, even those that
don't have subcommands.
- Introduce a specific parse_options_and_subcommand() variant
with that extra funcion parameter.
- I decided against automatically calling the subcommand function
from within parse_options(), because:
- There are commands that have to perform additional actions
after option parsing but before calling the function
implementing the specified subcommand.
- The return code of the subcommand is usually the return code
of the git command, but preserving the return code of the
automatically called subcommand function would have made the
API awkward.
- Also add a OPT_SUBCOMMAND_F() variant to allow specifying an
option flag: we have two subcommands that are purposefully
excluded from completion ('git remote rm' and 'git stash save'),
so they'll have to be specified with the PARSE_OPT_NOCOMPLETE
flag.
- Some of the 'parse_opt_flags' don't make sense with subcommands,
and using them is probably just an oversight or misunderstanding.
Therefore parse_options() will BUG() when invoked with any of the
following flags while the options array contains at least one
OPT_SUBCOMMAND:
- PARSE_OPT_KEEP_DASHDASH: parse_options() stops parsing
arguments when encountering a "--" argument, so it doesn't
make sense to expect and keep one before a subcommand, because
it would prevent the parsing of the subcommand.
However, this flag is allowed in combination with the
PARSE_OPT_SUBCOMMAND_OPTIONAL flag, because the double dash
might be meaningful for the command's default operation mode,
e.g. to disambiguate refs and pathspecs.
- PARSE_OPT_STOP_AT_NON_OPTION: As its name suggests, this flag
tells parse_options() to stop as soon as it encouners a
non-option argument, but subcommands are by definition not
options... so how could they be parsed, then?!
- PARSE_OPT_KEEP_UNKNOWN: This flag can be used to collect any
unknown --options and then pass them to a different command or
subsystem. Surely if a command has subcommands, then this
functionality should rather be delegated to one of those
subcommands, and not performed by the command itself.
However, this flag is allowed in combination with the
PARSE_OPT_SUBCOMMAND_OPTIONAL flag, making possible to pass
--options to the default operation mode.
- If the command with subcommands has a default operation mode, then
all arguments to the command must preceed the arguments of the
subcommand.
AFAICT we don't have any commands where this makes a difference,
because in those commands either only the command accepts any
arguments ('notes' and 'remote'), or only the default subcommand
('reflog' and 'stash'), but never both.
- The 'argv' array passed to subcommand functions currently starts
with the name of the subcommand. Keep this behavior. AFAICT no
subcommand functions depend on the actual content of 'argv[0]',
but the parse_options() call handling their options expects that
the options start at argv[1].
- To support handling subcommands programmatically in our Bash
completion script, 'git cmd --git-completion-helper' will now list
both subcommands and regular --options, if any. This means that
the completion script will have to separate subcommands (i.e.
words without a double dash prefix) from --options on its own, but
that's rather easy to do, and it's not much work either, because
the number of subcommands a command might have is rather low, and
those commands accept only a single --option or none at all. An
alternative would be to introduce a separate option that lists
only subcommands, but then the completion script would need not
one but two git invocations and command substitutions for commands
with subcommands.
Note that this change doesn't affect the behavior of our Bash
completion script, because when completing the --option of a
command with subcommands, e.g. for 'git notes --<TAB>', then all
subcommands will be filtered out anyway, as none of them will
match the word to be completed starting with that double dash
prefix.
[1] Except 'git rerere', because many of its subcommands are
implemented in the bodies of the if-else if statements parsing the
command's subcommand argument.
[2] Except 'credential', 'credential-store' and 'fsmonitor--daemon',
because some of the functions implementing their subcommands take
special parameters.

The description of 'PARSE_OPT_KEEP_UNKNOWN' starts with "Keep unknown
arguments instead of erroring out". This is a bit misleading, as this
flag only applies to unknown --options, while non-option arguments are
kept even without this flag.
Update the description to clarify this, and rename the flag to
PARSE_OPTIONS_KEEP_UNKNOWN_OPT to make this obvious just by looking at
the flag name.

In 't0040-parse-options.sh' we thoroughly test the parsing of all
types and forms of options, but in all those tests parse_options() is
always invoked with a 0 flags parameter.
Add a few tests to demonstrate how various 'enum parse_opt_flags'
values are supposed to influence option parsing.

Fix a memory leak in t/helper/test-parse-options.c, we were not
freeing the allocated "struct string_list" or its items. Let's move
the declaration of the "list" variable into the cmd__parse_options()

the "list" variable was added, and later on in
c8ba1639165 (parse-options: add OPT_STRING_LIST helper, 2011-06-09)
the "expect" was added.
The "list" variable was last touched in 2721ce21e43 (use string_list
initializer consistently, 2016-06-13), but it was still left at the
static scope, it's better to move it to the function for consistency.

There were no tests for checking the specific output that we'll
generate in optname(), let's add some. That output was added back in

As was noted in 1a85b49b87a (parse-options: make OPT_ARGUMENT() more
useful, 2019-03-14) there's only ever been one user of the
OPT_ARGUMENT(), that user was added in 20de316e334 (difftool: allow
running outside Git worktrees with --no-index, 2019-03-14).
The OPT_ARGUMENT() feature itself was added way back in
580d5bffdea (parse-options: new option type to treat an option-like
parameter as an argument., 2008-03-02), but as discussed in
1a85b49b87a wasn't used until 20de316e334 in 2019.
Now that the preceding commit has migrated this code over to using
"struct strvec" to manage the "args" member of a "struct
child_process", we can just use that directly instead of relying on
OPT_ARGUMENT.
This has a minor change in behavior in that if we'll pass --no-index
we'll now always pass it as the first argument, before we'd pass it in
whatever position the caller did. Preserving this was the real value
of OPT_ARGUMENT(), but as it turns out we didn't need that either. We
can always inject it as the first argument, the other end will parse
it just the same.
Note that we cannot remove the "out" and "cpidx" members of "struct
parse_opt_ctx_t" added in 580d5bffdea, while they were introduced with
OPT_ARGUMENT() we since used them for other things.

There is a long-standing NEEDSWORK comment that complains about
inconsistency between how an aliased option ("git clone --recurse"
which is the only one that currently exists) gives a help text in
a usage-error message vs "git cmd -h"). Get rid of it and then
make sure we say an option is an alias for another, instead of
repeating the same short help text for both, which leads to "they
seem to do the same---is there any subtle difference?" puzzlement
to end-users.

"git am --short-current-patch" is a way to show the piece of e-mail

The revision option parser recently learned about --end-of-options, but
that's not quite enough for all callers. Some of them, like git-log,
pick out some options using parse_options(), and then feed the remainder
to setup_revisions(). For those cases we need to stop parse_options()
from finding more options when it sees --end-of-options, and to retain
that option in argv so that setup_revisions() can see it as well.
Let's handle this the same as we do "--". We can even piggy-back on the
handling of PARSE_OPT_KEEP_DASHDASH, because any caller that wants to
retain one will want to retain the other.
I've included two tests here. The "log" test covers "--source", which is
one of the options it handles with parse_options(), and would fail
before this patch. There's also a test that uses the parse-options
helper directly. That confirms that the option is handled correctly even
in cases without KEEP_DASHDASH or setup_revisions(). I.e., it is safe to
use --end-of-options in place of "--" in other programs.

Change the option parsing machinery so that e.g. "clone --recurs ..."
doesn't error out because "clone" understands both "--recursive" and
"--recurse-submodules" to mean the same thing.
Initially "clone" just understood --recursive until the
--recurses-submodules alias was added in ccdd3da652 ("clone: Add the
--recurse-submodules option as alias for --recursive",
2010-11-04). Since bb62e0a99f ("clone: teach --recurse-submodules to
optionally take a pathspec", 2017-03-17) the longer form has been
promoted to the default.
But due to the way the options parsing machinery works this resulted
in the rather absurd situation of:
$ git clone --recurs [...]
error: ambiguous option: recurs (could be --recursive or --recurse-submodules)
Add OPT_ALIAS() to express this link between two or more options and use
it in git-clone. Multiple aliases of an option could be written as
OPT_ALIAS(0, "alias1", "original-name"),
OPT_ALIAS(0, "alias2", "original-name"),
...
The current implementation is not exactly optimal in this case. But we
can optimize it when it becomes a problem. So far we don't even have two
aliases of any option.
A big chunk of code is actually from Junio C Hamano.

Git's command-line parsers support uniquely abbreviated options, e.g.
`git init --ba` would automatically expand `--ba` to `--bare`.
This is a very convenient feature in every day life for Git users, in
particular when tab completion is not available.
However, it is not a good idea to rely on that in Git's test suite, as
something that is a unique abbreviation of a command line option today
might no longer be a unique abbreviation tomorrow.
For example, if a future contribution added a new mode
`git init --babyproofing` and a previously-introduced test case used the
fact that `git init --ba` expanded to `git init --bare`, that future
contribution would now have to touch seemingly unrelated tests just to
keep the test suite from failing.
So let's disallow abbreviated options in the test suite by default.
Note: for ease of implementation, this patch really only touches the
`parse-options` machinery: more and more hand-rolled option parsers are
converted to use that internal API, and more and more scripts are
converted to built-ins (naturally using the parse-options API, too), so
in practice this catches most issues, and is definitely the biggest bang
for the buck.

There are no users of OPT_DATE except for test-parse-options; its
only caller went away in 27ec394a97 (prune: introduce OPT_EXPIRY_DATE()
and use it, 2013-04-25).
It also has a bug: it does not specify PARSE_OPT_NONEG, but its callback
does not respect the "unset" flag, and will feed NULL to approxidate()
and segfault. Probably this should be marked with NONEG, or the callback
should set the timestamp to some sentinel value (e.g,. "0", or
"(time_t)-1").
But since there are no callers, deleting it means we don't even have to
think about what the right behavior should be.

Using 'test_must_be_empty' is shorter and more idiomatic than
>empty &&
test_cmp empty out
as it saves the creation of an empty file. Furthermore, sometimes the
expected empty file doesn't have such a descriptive name like 'empty',
and its creation is far away from the place where it's finally used
for comparison (e.g. in 't7600-merge.sh', where two expected empty
files are created in the 'setup' test, but are used only about 500
lines later).
These cases were found by instrumenting 'test_cmp' to error out the
test script when it's used to compare empty files, and then converted
manually.
Note that even after this patch there still remain a lot of cases
where we use 'test_cmp' to check empty files:
- Sometimes the expected output is not hard-coded in the test, but
'test_cmp' is used to ensure that two similar git commands produce
the same output, and that output happens to be empty, e.g. the
test 'submodule update --merge - ignores --merge for new
submodules' in 't7406-submodule-update.sh'.
- Repetitive common tasks, including preparing the expected results
and running 'test_cmp', are often extracted into a helper
function, and some of this helper's callsites expect no output.
- For the same reason as above, the whole 'test_expect_success'
block is within a helper function, e.g. in 't3070-wildmatch.sh'.
- Or 'test_cmp' is invoked in a loop, e.g. the test 'cvs update
(-p)' in 't9400-git-cvsserver-server.sh'.

When the option spec contains no switches or only hidden switches,
parse_options will emit an extra blank line at the end of help output so
that the help text will end in two blank lines instead of one.
When parse_options produces internal help output after an error has
occurred it will emit blank lines within the usage string to stdout
instead of stderr.
Update t/helper/test-parse-options.c to have a description body in the
usage string to exercise this second bug and mark tests as failing in
t0040.
Add tests to t1502 to demonstrate both of these problems.

Existing tests in t0040 follow a rather verbose pattern:
cat >expect <<\EOF
boolean: 0
integer: 0
magnitude: 0
timestamp: 0
string: (not set)
abbrev: 7
verbose: 0
quiet: 3
dry run: no
file: (not set)
EOF
test_expect_success 'multiple quiet levels' '
test-parse-options -q -q -q >output 2>output.err &&
test_must_be_empty output.err &&
test_cmp expect output
'
But the only thing this test cares about is if "quiet: 3" is in the
output. We should be able to write the above 18 lines with just
four lines, like this:
test_expect_success 'multiple quiet levels' '
test-parse-options --expect="quiet: 3" -q -q -q
'

When test-parse-options detects an error on the command line, it
gives the usage string just like any parse-options API users do,
without showing any "variable dump". An exception is the callback
test, where a "variable dump" for the option is done before the
command line options are fully parsed.
Do not expose this implementation detail by separating the handling
of callback test into two phases, one to capture the fact that an
option was given during the option parsing phase, and the other to
show that fact as a part of normal "variable dump".
The effect of this fix is seen in the patch to t/t0040 where it
tried "test-parse-options --no-length" where "--length" is a callback
that does not take a negative form.

OPT_COUNTUP() merely increments the counter upon --option, and resets it
to 0 upon --no-option, which means that there is no "unspecified" value
with which a client can initialize the counter to determine whether or
not --[no]-option was seen at all.
Make OPT_COUNTUP() treat any negative number as an "unspecified" value
to address this shortcoming. In particular, if a client initializes the
counter to -1, then if it is still -1 after parse_options(), then
neither --option nor --no-option was seen; if it is 0, then --no-option
was seen last, and if it is 1 or greater, than --option was seen last.
This change does not affect the behavior of existing clients because
they all use the initial value of 0 (or more).
Note that builtin/clean.c initializes the variable used with
OPT__FORCE (which uses OPT_COUNTUP()) to a negative value, but it is set
to either 0 or 1 by reading the configuration before the code calls
parse_options(), i.e. as far as parse_options() is concerned, the
initial value of the variable is not negative.
To test this behavior, in test-parse-options.c, "verbose" is set to
"unspecified" while quiet is set to 0 which will test the new behavior
with all sets of values.

The unsigned long option parsing (including 'k'/'m'/'g' suffix
parsing) is more widely applicable. Add support for OPT_MAGNITUDE
to parse-options.h and change pack-objects.c use this support.
The error behavior on parse errors follows that of OPT_INTEGER. The
name of the option that failed to parse is reported with a brief
message describing the expect format for the option argument and
then the full usage message for the command invoked.
This differs from the previous behavior for OPT_ULONG used in
pack-objects for --max-pack-size and --window-memory which used to
display the value supplied in the error message and did not display
the full usage message.
