From ab07ba2a2436cc717b872387320297bb806d35d9 Mon Sep 17 00:00:00 2001 From: Markus Heidelberg Date: Wed, 22 Apr 2009 23:41:25 +0200 Subject: [PATCH] show-branch: color the commit status signs Make it possible to color the status character ('*' '!' '+' '-') of each commit corresponding to the branch it's in. This makes it easier to follow a particular branch, especially if there are larger gaps in the output. Add the config option color.showbranch and the command line options --color and --no-color to control the colored output.
