When mailmap is enabled by default or by configuration, it may be
useful to override the default behaviour.  Previously, it was
possible to enable the mailmap feature when it was disabled by
default or in the configuration, but it was not possible to disable
the mailmap feature when it was enabled by default or by the
configuration.

The --no-use-mailmap option equalizes this by allowing the user to
explicitly enable or disable the mailmap feature according to their
requirements.
