You can do it this way:

1. In your personal bin or whatever, symbolically link "forw" to "repl".

2. Make a file in your "Mail" directory called "components.forw" or some
   such, containing:

	To: \n\
	Cc: \n\
	%<{subject}Subject: [%(lit)%(pers{from})%<(nonnull)%|%{from}%>: %{subject}]\n%|Subject: \n%>\
	Fcc: outbox\n\
	Bcc: \n\
	--------

   (The "Subject" line above should be all one line; don't let your newsreader
   break it.)

3. Make another file in your "Mail" directory called "mhl.forw" or some
   such, containing:

	width=80,overflowtext=,overflowoffset=0
	leftadjust,compress,compwidth=9
	:
	:------- Forwarded Message
	:
	From:
	To:
	Cc:
	Date:formatfield="%<(nodate{text})%{text}%|%(tws{text})%>"
	Subject:
	:
	body:nocomponent,overflowoffset=0,noleftadjust,nocompress
	:
	:------- End of Forwarded Message

   You need this now to add the "Forwarded Message" lines around the original,
   since you're not using the real "forw" anymore.

4. Edit your .mh_profile and add:

	forw: -filter mhl.forw -form components.forw

The reason you have to do it this way is that "repl" is the only MH program
that lets you grab fields out of the replied-to (forwarded) message and put
them in the new message's headers.

P.S. - The above components file will put the person's name and subject in
       the new subject line.  For example, if I ran it on your original
       message, I'd get:

		Subject: [Tony Jones: forw & subject lines]

       Of course, you can change the line to do "foobar (fwd)" like you want.

[ Good explanation of how to do this with repl. ]

The main problem with this technique is that repl can't do
"dashmunging".  This is necessary if you want the recipient to be able
to use burst to extract the original message and the original contains
lines that start with dashes.  Also, if you forward a forwarded message,
the resulting message becomes completely unparseable by burst.

I wish there were a good way of combining the features of forw and
repl.
