Replying to Mail
----------------

   If you find that most of the time that you specify `cc' when you
reply to a message, set `mh-reply-default-reply-to' to `cc'.  This
variable is normally set to `nil' so that you are prompted for the
recipient of a reply.  It can be set to one of `from', `to', or `cc';
you are then no longer prompted for the recipient(s) of your reply.
