contrib: contacts: add mailmap support
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 As such, it is important to report up-to-date email addresses in the computed list rather than potentially outdated ones recorded with commits.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. Signed-off-by: Eric Sunshine <sunshine@sunshineco.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
