The purpose of git-contacts is to determine a list of people who might
have some interest in a patch or set of changes. It can be used as
git-send-email's --cc-cmd argument or the computed list might be used to
ask for comments on a proposed change. As such, it is important to
report up-to-date email addresses in the computed list rather than
potentially outdated ones recorded with commits. Apply git's mailmap
functionality to the retrieved contacts in order to achieve this goal.
