From: Bo Yang Date: Wed, 26 May 2010 07:23:54 +0000 (+0800) Subject: diff.c: Output the text graph padding before each diff line X-Git-Tag: v1.7.2-rc0~44^2~3 X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=7be5761;p=git.git diff.c: Output the text graph padding before each diff line Change output from diff with -p/--dirstat/--binary/--numstat/--stat/ --shortstat/--check/--summary options to align with graph paddings. Thanks Jeff King for reporting the '--summary' bug and his initial patch.
