Nguyễn Thái Ngọc Duy 8f4f8f4579 guard against new pathspec magic in pathspec matching code
GUARD_PATHSPEC() marks pathspec-sensitive code, basically all those
that touch anything in 'struct pathspec' except fields "nr" and
"original". GUARD_PATHSPEC() is not supposed to fail. It's mainly to
help the designers catch unsupported codepaths.
