Subject: [RFC/PATCH 1/4] builtin: add git-check-mailmap command
Date: Wed, 10 Jul 2013 15:03:58 -0400 [thread overview]
Message-ID: <1373483041-27901-2-git-send-email-sunshine@sunshineco.com> (raw)
In-Reply-To: <1373483041-27901-1-git-send-email-sunshine@sunshineco.com>
Introduce command check-mailmap, similar to check-attr and check-ignore,
which allows direct testing of .mailmap configuration.
As plumbing accessible to scripts and other porcelain, check-mailmap
publishes the stable, well-tested .mailmap functionality employed by
built-in Git commands. Consequently, script authors need not
re-implement .mailmap functionality manually, thus avoiding potential
quirks and behavioral differences.
