From 5761231975ceffa531d86d9bab0f9a9a370674f6 Mon Sep 17 00:00:00 2001 From: Junio C Hamano Date: Sat, 16 Dec 2006 16:07:20 -0800 Subject: [PATCH] Make left-right automatic. When using symmetric differences, I think the user almost always would want to know which side of the symmetry each commit came from. So this removes --left-right option from the command line, and turns it on automatically when a symmetric difference is used ("git log --merge" counts as a symmetric difference between HEAD and MERGE_HEAD). Just in case, a new option --no-left-right is provided to defeat this, but I do not know if it would be useful.
