Some workflows prefer to track exactly which email message was used to
generate a commit. This can be used, for example, to generate an
automated acknowledgement when a patch is committed as a response to
the patch email, or as a reference to the thread which introduced the
patch.
Support this by adding a --message-id option (abbreviated as -m) to
git-am, which will then extract the message ID and append it to the
email commit log.
