Hmm, now I have.

As far as I understand, all the git-am hooks are called on the commit
rather than the incoming email: all headers are lost by the time
git-mailinfo exits, including the Message-Id.  And you cannot call any
hook before git-mailinfo because git-mailinfo is where the
Content-Transfer-Encoding is processed.

How would you integrate git-interpret-trailers in git-mailinfo?
