Add a new function, is_shared_symref(), which contains the heart of
find_shared_symref(). Refactor find_shared_symref() to use the new
function is_shared_symref().
Soon, we will use is_shared_symref() to search for symref beyond
the first worktree that matches.

Replace non-existent `branch.<name>.fetch` to `remote.<repository>.fetch`, in
the first example in `git-fetch` doc, which was introduced in
d504f6975d (modernize fetch/merge/pull examples, 2009-10-21).
Rename placeholder `<name>` to `<repository>`, to be consistent with all other
uses in git docs, except that `git-config.txt` uses `remote.<name>.fetch` in
its "Variables" section.
Also add missing monospace markups.

As per the code comment, the `.git/head-name` files were cleaned up for
backwards-compatibility: an old version of `git bisect` could have left
them behind.
Now, just how old would such a version be? As of 0f497e75f05 (Eliminate
confusing "won't bisect on seeked tree" failure, 2008-02-23), `git
bisect` does not write that file anymore. Which corresponds to Git
v1.5.4.4.
Even if the likelihood is non-nil that there might still be users out
there who use such an old version to start a bisection, but then decide
to continue bisecting with a current Git version, it is highly
improbable.
So let's remove that code, at long last.

Once upon a time, there was this idea that Git would not actually be a
single coherent program, but rather a set of low-level programs that
users cobble together via shell scripts, or develop high-level user
interfaces for Git, or both.
Cogito was such a high-level user interface, incidentally implemented
via shell scripts that cobble together Git calls.
It did turn out relatively quickly that Git would much rather provide a
useful high-level user interface itself.
As of April 19th, 2007, Cogito was therefore discontinued (see
https://lore.kernel.org/git/20070419124648.GL4489@pasky.or.cz/).
Nevertheless, for almost 15 years after that announcement, Git carried
special code in `git bisect` to accommodate Cogito.
Since it is beyond doubt that there are no more Cogito users, let's
remove the last remnant of Cogito-accommodating code.

In d1bbbe45df8 (bisect--helper: reimplement `bisect_run` shell function
in C, 2021-09-13), we ported the `bisect run` subcommand to C, including
the part that prints out an error message when the implicit `git bisect
bad` or `git bisect good` failed.
However, the error message was supposed to print out whether the state
was "good" or "bad", but used a bogus (because non-populated) `args`
variable for it. This was fixed in [1], but as of [2] (when
`bisect--helper` was changed to the present `bisect-state') the error
message still talks about implementation details that should not
concern end users.
Fix that, and add a regression test to ensure that the intended form of
the error message.

We do not want `git bisect --bogus-option` to start a bisection. To
verify that, we look for the tell-tale error message `You need to start
by "git bisect start"` and fail if it was found.

In C, the natural order is for `argc` to come before `argv` by virtue of
the `main()` function declaring the parameters in precisely that order.
It is confusing & distracting, then, when readers familiar with the C
language read code where that order is switched around.
Let's just change the order and avoid that type of developer friction.

The "ls-tree" command isn't capable of ending "lines" with anything
except '\n' or '\0', and in the latter case we can avoid calling
write_name_quoted_relative() entirely. Let's do that, less for
optimization and more for clarity, the write_name_quoted_relative()
API itself does much the same thing.

After the the preceding two commits the only user of the

As a first step towards being able to turn this code into an API some
day let's change the "static" options in builtin/ls-tree.c into a
"struct ls_tree_options" that can be constructed dynamically without
the help of parse_options().
Because we're now using non-static variables for this we'll need to
clear_pathspec() at the end of cmd_ls_tree(), least various tests
start failing under SANITIZE=leak. The memory leak was already there
before, now it's just being brought to the surface.

As noted in [1] the code that made it in as part of
9c4d58ff2c3 (ls-tree: split up "fast path" callbacks, 2022-03-23) was
a "maybe a good idea, maybe not" RFC-quality patch. I hadn't looked
very carefully at the resulting patterns.
The implementation shared the "struct show_tree_data data", which was
introduced in e81517155e0 (ls-tree: introduce struct "show_tree_data",
2022-03-23) both for use in 455923e0a15 (ls-tree: introduce "--format"
option, 2022-03-23), and because the "fat" callback hadn't been split
up as 9c4d58ff2c3 did.
Now that that's been done we can see that most of what
show_tree_common() was doing could be done lazily by the callbacks
themselves, who in the pre-image were often using an odd mis-match of
their own arguments and those same arguments stuck into the "data"
structure. Let's also have the callers initialize the "type", rather
than grabbing it from the "data" structure afterwards.

ISO 8601 permits "reduced precision" time representations to omit the
seconds value or both the minutes and the seconds values. The
abbreviate times could look like 17:45 or 1745 to omit the seconds,
or simply as 17 to omit both the minutes and the seconds.
parse_date_basic accepts the 17:45 format but it rejects the other two.
Change it to accept 4-digit and 2-digit time values when they follow a
recognized date and a 'T'.
Before this change:

2022-12-13T23 -> 2022-12-13 23:00:00 +0000
Note: ISO 8601 also allows reduced precision date strings such as
"2022-12" and "2022". This patch does not attempt to address these.

When handling "--exec" rebase collects the commands into a struct
string_list, then prepends "exec " to each command creating a multi line
string and finally splits that string back into a list of commands. This
is an artifact of the scripted rebase and the need to support "rebase
--preserve-merges". Now that "--preserve-merges" no-longer exists we can
cleanup the way the argument is handled. There is no need to add the
"exec " prefix to the commands as that is added by todo_list_to_strbuf().

'ORIG_HEAD' is written at the start of the rebase, but is not guaranteed
to still point to the original branch tip at the end of the rebase.
Indeed, using other commands that write 'ORIG_HEAD' during the rebase,
like splitting a commit using 'git reset HEAD^', will lead to 'ORIG_HEAD'
being overwritten. This causes confusion for some users [1].
Add a note about that in the 'Description' section, and mention the more
robust alternative of using the branch's reflog.

Commit 67ac1e1d57 (cherry-pick/revert: add support for
-X/--strategy-option, 2010-12-10) added an example to the documentation
of 'git cherry-pick'. This example mentions how to abort a failed
cherry-pick and retry with an additional merge strategy option.
The command used in the example to abort the cherry-pick is 'git reset
--merge ORIG_HEAD', but cherry-pick does not write 'ORIG_HEAD' before
starting its operation. So this command would checkout a commit
unrelated to what was at HEAD when the user invoked cherry-pick.
Use 'git cherry-pick --abort' instead.

In the "DETACHED HEAD" section in the git-checkout doc, it suggests
using "git checkout -b <branch-name>" to create a new branch on the
detached head.
On the other hand, when you checkout a commit that is not at the tip of
any named branch (e.g., when you checkout a tag), git suggests using
"git switch -c <branch-name>".
Add "git switch -c" as another option and mitigate this inconsistency.

The interop test library sets up wrappers "git.a" and "git.b" to
represent the two versions to be tested. It also wraps vanilla "git" to
report an error, with the goal of catching tests which accidentally fail
to use one of the version-specific wrappers (which could invalidate the
tests in a very subtle way).
But when it catches an invocation of vanilla git, it doesn't give any
details, which makes it very hard to debug exactly which invocation is
responsible (especially if it's buried in a function invocation, etc).
Let's report the arguments passed to git, which helps narrow it down.

2017-04-20) replaced a dead link to news release on nist.gov. However,
this might be confusing to the reader (like myself) because the article
git-bisect-lk2009.txt quotes from the news release but the exact quote
cannot be found in the full report. In addition to that, the link added
in 2017 is also dead in 2023.
Replace the reference to nist.gov with an version of the original NIST
news release archived to the Wayback Machine. Include also an updated
link to a live version of the full report.

A reference to Java Code Conventions in git-bisect-lk2009.txt uses an
outdated URL that redirects to table of contents for the conventions.
The actual claim about "80%" that this reference backs up is on the
first page of the conventions:
https://www.oracle.com/java/technologies/javase/codeconventions-introduction.html
Use this newer URL and its title in the reference.

Most tests in t7527-builtin-fsmonitor.sh that start a daemon, use the
helper function test_when_finished with stop_daemon_delete_repo.
Function stop_daemon_delete_repo explicitly stops the daemon. Calling
it via test_when_finished is needed for tests that don't check daemon's
automatic shutdown logic [1] and it is needed to avoid daemons being
left running in case of breakage of the logic of automatic shutdown of
the daemon.
Unlike these tests, test 'case insensitive+preserving' added in [2] has
a call to function test_when_finished commented out. It was commented
out in all versions of the patch [2] during development [3]. This seems
to not be intentional, because neither commit message in [2], nor the
comment above the test mention this line being commented out. Compare
it, for example, to "# unicode_debug=true" which is explicitly described
by a documentation comment above it.
Uncomment test_when_finished for stop_daemon_delete_repo in test 'case
insensitive+preserving' to ensure that daemons are not left running in
cases when automatic shutdown logic of daemon itself is broken.

In commit [1] tests in t6422-merge-rename-corner-cases.sh were
refactored to not run setup steps separately. This included replacing
all tests like
test_expect_success "setup ..." '
<code of setup>
'
with corresponding Shell functions
test_setup_... () {
<code of setup>
}
During this replacement first and last lines of one of such tests got
left commented out in code. Drop these lines to avoid confusion.

Test '--max-age=c3, --topo-order' in t6003-rev-list-topo-order.sh has
been commented out as failing since its introduction in [1]. However,
the test is successful at least since commit [2] -- bisecting further is
harder because of incompatibility of such old Git code with modern
header file <openssl/bn.h> [3].
Uncomment this test to gain test coverage.

Currently, in the git-log documentation, the reference to generating
patches does not match the section title. This can make the section
"Generating patch text with -p" hard to find, since typically readers of
the documentation will copy and paste to search the page.
Let's make this more convenient for readers by linking it directly to
the section.
Since git-log pulls in diff-generate-patch.txt, we can provide a direct
link to the section. Otherwise, change the verbiage to match exactly
what the section title is, to at least make searching for it an easier
task.

Hook authors are periodically caught off-guard by difficult-to-diagnose
errors when their hook invokes Git commands in a repository other than
the local one. In particular, Git environment variables, such as GIT_DIR
and GIT_WORK_TREE, which reference the local repository cause the Git
commands to operate on the local repository rather than on the
repository which the author intended. This is true whether the
environment variables have been set manually by the user or
automatically by Git itself. The same problem crops up when a hook
invokes Git commands in a different worktree of the same repository, as
well.
Recommended best-practice[1,2,3,4,5,6] for avoiding this problem is for
the hook to ensure that Git variables are unset before invoking Git
commands in foreign repositories or other worktrees:
unset $(git rev-parse --local-env-vars)
However, this advice is not documented anywhere. Rectify this
shortcoming by mentioning it in githooks.txt documentation.

Add a macro for allocating and populating a shallow copy of an array.
It is intended to replace a sequence like this:
ALLOC_ARRAY(dst, n);
COPY_ARRAY(dst, src, n);
With the less repetitve:
DUP_ARRAY(dst, src, n);
It checks whether the types of source and destination are compatible to
ensure the copy can be used safely.
An easier alternative would be to only consider the source and return
a void pointer, that could be used like this:
dst = ARRAY_DUP(src, n);
That would be more versatile, as it could be used in declarations as
well. Making it type-safe would require the use of typeof_unqual from
C23, though.
So use the safe and compatible variant for now.

Use __builtin_types_compatible_p to perform a full type check if
possible. Otherwise fall back to the old size comparison, but add a
non-evaluated assignment to catch more type mismatches. It doesn't flag
copies between arrays with different signedness, but that's as close to
a full type check as it gets without the builtin, as far as I can see.

Move the common basic element type check of COPY_ARRAY and MOVE_ARRAY to
a new macro. This reduces code duplication and simplifies adding more
elaborate checks.
