 1.3 Reply
 =========
 
 The ‘message-reply’ function pops up a message buffer that’s a reply to
 the message in the current buffer.
 
    Message uses the normal methods to determine where replies are to go
 (SeeResponses), but you can change the behavior to suit your needs
 by fiddling with the ‘message-reply-to-function’ variable.
 
    If you want the replies to go to the ‘Sender’ instead of the ‘From’,
 you could do something like this:
 
      (setq message-reply-to-function
            (lambda ()
             (cond ((equal (mail-fetch-field "from") "somebody")
                     (list (cons 'To (mail-fetch-field "sender"))))
                   (t
                    nil))))
 
    This function will be called narrowed to the head of the article that
 is being replied to.
 
    As you can see, this function should return a list.  In this case, it
 returns ‘((To . "Whom"))’ if it has an opinion as to what the To header
 should be.  If it does not, it should just return ‘nil’, and the normal
 methods for determining the To header will be used.
 
    Each list element should be a cons, where the CAR should be the name
 of a header (e.g., ‘Cc’) and the CDR should be the header value (e.g.,
 ‘larsi@ifi.uio.no’).  All these headers will be inserted into the head
 of the outgoing mail.
