From 8a3685bcf2612206fc24a2421acb53dd83aeab85 Mon Sep 17 00:00:00 2001 From: Lars Hjemli Date: Sun, 13 May 2007 22:25:14 +0200 Subject: Add graphical diffstat to commit view The diffstat is calculated against the leftmost parent of the commit. This gives nice information for "normal" merges while octopus merges are less than optimal, so the diffstat isn't calculated for those merges.
