Basically notmuch layers its own stuff on top of message mode.

Except `message-user-agent` gets used instead of `notmuch-user-agent`
which does the layering on top. We currently don't do much more, but
might in the future. As an example, `notmuch-mua-send-hook` won't get
called.

Another question open to debate is, if the user is using the notmuch
interface, and calls a function named `notmuch-mua-new-mail` to compose
mail, should the function respect `mail-user-agent` and pop up a
non-notmuch interface? Basically what we do is tested to work on top of
message mode only, so all bets would be off anyway.

Jani.
