I really think we need to investigate having a notmuch-message-mode as
there are now a number of reasons to be able to customize things when
the user is running notmuch.

BTW: I don't think these are "promotion headers" - I relatively
frequently want to check which email client someone else is using when
I'm trying to figure out why things go wrong (incorrect mail headers,
mangled spacing (in patches, for example), incorrect HTML messages, etc)
