[PATCH v2 1/3] log: use mailmap by default

[Ariadne Conill <ariadne@dereferenced.org>]

The `git log` command shows the author and committer name recorded in
the git repository itself, while other commands respect `.mailmap`
by default.  I believe this is a bad design: it causes log entries to
reflect inaccurate information: anyone who changes their name or
e-mail address will not have that change (recorded in mailmap file)
reflected when using `git log` by default.

Anyone who explicitly wants the current behaviour can clearly request
it by setting the `log.mailmap` setting to `false` in their
`.gitconfig` file.
