From d72fbe8111fbd3083d7063078c96eed27098490c Mon Sep 17 00:00:00 2001 From: Antoine Pelisse Date: Sat, 5 Jan 2013 22:26:45 +0100 Subject: [PATCH] log: grep author/committer using mailmap Currently you can use mailmap to display log authors and committers but you can't use the mailmap to find commits with mapped values. This commit allows you to run: git log --use-mailmap --author mapped_name_or_email git log --use-mailmap --committer mapped_name_or_email Of course it only works if the --use-mailmap option is used. The new name and email are copied only when necessary.
