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.) Signed-off-by: Abhijit Menon-Sen <ams@toroid.org> Signed-off-by: Junio C Hamano <gitster@pobox.com>
