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.
