From 46a0431b996cd19f21e0247c97b1eab2c19698fc Mon Sep 17 00:00:00 2001 From: Bert Wesarg Date: Mon, 15 Nov 2010 11:00:33 +0100 Subject: [PATCH] git-gui: fix ANSI-color parsing git diff always outputs color reset commands, even when the color for the current part is disabled (ie. normal). But the current ANSI-color parsing code assumes that color start and reset commands appear in matching pairs. Relax this assumption.
