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. Signed-off-by: Nguyễn Thái Ngọc Duy <pclouds@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
