Subject: [PATCH] gitweb: Map names/emails with mailmap
Date: Sat, 8 Aug 2020 21:34:58 +0000 [thread overview]
Message-ID: <20200808213457.13116-1-me@pluvano.com> (raw)
In-Reply-To: <20200730041217.6893-1-me@pluvano.com>
Add an option to map names and emails to their canonical forms via a
.mailmap file. This is enabled by default, consistent with the behavior
of Git itself.
