Git.pm: localise $? in command_close_bidi_pipe()
Git::DESTROY calls _close_cat_blob and _close_hash_and_insert_object,
which in turn call command_close_bidi_pipe, which calls waitpid, which
alters $?. If this happens during global destruction, it may alter the
program's exit status unexpectedly. Making $? local to the function
solves the problem.
(The problem was discovered due to a failure of test #8 in
t9106-git-svn-commit-diff-clobber.sh.)
