Merge branch 'jk/save-getenv-result'
There were many places the code relied on the string returned from
getenv() to be non-volatile, which is not true, that have been
corrected.
* jk/save-getenv-result:
builtin_diff(): read $GIT_DIFF_OPTS closer to use
merge-recursive: copy $GITHEAD strings
init: make a copy of $GIT_DIR string
config: make a copy of $GIT_CONFIG string
commit: copy saved getenv() result
get_super_prefix(): copy getenv() result
