Previously, cleanup_git() would use `test_must_fail test -d` to ensure that the directory is removed. However, test_must_fail should only be used for git commands. Use test_path_is_missing() instead to check that the directory has been removed. Signed-off-by: Denton Liu <liu.denton@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
