You currently get (1), which is arguably the most precise but definitely
the ugliest.

In this case (posting as maintainer), I would probably not use "git am
--message-id"; instead I would use an alias to add the Message-Id (with
git interpret-trailers!) after posting to the mailing list, resulting in
either (2) or (3).

I think (but I am not sure) that git-am could use a hook to rewrite (1)
into (2) or (3).
