When composing messages (including replies, etc.), indicate to
`message-mode' definitively that the message is email (as opposed to
Usenet news) rather than having it attempt to determine this for itself.
This causes `message-mode' to observe such variables as
`message-default-mail-headers', which previously happened haphazardly.
;; We need to convert any string input, eg from rmail-start-mail.
(dolist (h other-headers other-headers)
(if (stringp (car h)) (setcar h (intern (capitalize (car h))))))))

;; message-setup-1 in Emacs 23 does not accept return-action
;; argument. Pass it only if it is supplied by the caller. This
