[Message part 1 (text/plain, inline)]

(Creating a bug report from a mail thread on emacs-devel to keep it
alive.  I probably should have done this as a bug report originally.
Original thread on http://permalink.gmane.org/gmane.emacs.devel/175920)

Does anyone have any further thoughts?  I consider existing behaviour a
bug, and I believe my patch fixes it in a relatively unobtrusive manner.
message.el is already autoloaded today, and my patch does not change
behaviour if the user has already told message.el how to determine
envelope-from, or if the guessed address would be sane.
