Forwarding Mail
---------------

   When forwarding a message, the format of the `Subject:' header field
can be modified by the variable `mh-forward-subject-format'.  This
variable is a string which includes two escapes (`%s').  The first `%s'
is replaced with the sender of the original message, and the second one
is replaced with the original `Subject:'.  The default value of `"%s:
%s"' takes a message with the header:

     To: Bill Wohler <wohler@newt.com>
     Subject: Re: 49er football
     From: Greg DesBrisay <gd@cellnet.com>

   and creates a subject header field of:

     Subject: Greg DesBrisay: Re: 49er football
