From 96afa0764e6b58a38b21befded2c8fd0543fab2a Mon Sep 17 00:00:00 2001 From: Junio C Hamano Date: Tue, 11 Apr 2006 23:05:14 -0700 Subject: [PATCH] Add colordiff for git to contrib/colordiff. I hacked it up to teach it the git extended diff headers, made it not to read the whole patch in the array. Also, the original program, when arguments are given, ran "diff" with the given arguments and showed the output from it. Of course, I changed it to run "git diff" ;-).
