I noticed that The Listserver for WWW-talk and WWW-html is not
perserving the In-Reply-To headers, e.g.

In-Reply-To: <9406161944.AA02482@ulua.hal.com>

So, unless people put these references in the body of the message, they
are going to get lost.  Bad.

If these were preserved, then the archive maintainers could do better
threading (e.g.,
http://gummo.stanford.edu/html/hypermail/www-talk-1994q2.messages/970.html)

There are probably other useful headers that should be preserved, like:

	X-URL

	X-URI

	Included-Messages

Basically, any header that refers to a MESAGE-ID or some kind of URL/URI
should be preserved.
