From bb9e15a83c425ff31e4da6b004bd4557d528b755 Mon Sep 17 00:00:00 2001 From: Uwe Zeisberger Date: Wed, 21 Jun 2006 11:04:12 +0200 Subject: [PATCH] Fix possible out-of-bounds array access If match is "", match[-1] is accessed. Let pathspec_matches return 1 in that case indicating that "" matches everything. Incidently this fixes git-grep'ing in ".".
