Mail thread references in commits

I love seeing references to email threads in commit messages. It would 
make them a lot friendlier though if a full http URL were included 
instead of just a Message-ID, i.e. instead of <foo1234@bar.com> put 
<https://www.postgresql.org/message-id/foo1234@bar.com>. I know this is 
a bit more trouble. but not that much, and it would make it very easy to 
follow with just a mouse click.

cheers
