After thinking about this some more, I think using defvaralias is a bad
idea.

Would anyone object to setting the default values for the message-mode
variables to the corresponding mail-mode variables? e.g.,

(defcustom message-from-style
    (if (featurep 'xemacs) 'angles mail-from-style)
    ....)

Any objections to adding a new user option message-run-mail-hooks,
which, if non-nil, causes message mode to run the corresponding mail
hooks as well?
