From c0c35d5e419f3bf215103b1e26359aca288c2113 Mon Sep 17 00:00:00 2001 From: Linus Torvalds Date: Wed, 16 Nov 2005 09:38:46 -0800 Subject: [PATCH] Disallow empty pattern in "git grep" 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.
