For some reason I've done a "git grep" twice with no pattern, which is really irritating, since it just grep everything. If I actually wanted that, I could do "git grep ^" or something. So add a "usage" message if the pattern is empty. Signed-off-by: Linus Torvalds <torvalds@osdl.org> Signed-off-by: Junio C Hamano <junkio@cox.net>
