So your proposed change is that `notmuch-mua-mail` should start
whichever mua the user has configured in `mail-user-agent` instead of
the notmuch mail composition window, as described in the function

Maybe we should let bind `mail-user-agent` instead?

I understand you're annoyed at the current behaviour, but please don't
pour that annoyance into notmuch NEWS. Thank you.
