Hmm.. what *should* happen with RFC2369 List-FOO headers?

Let's say you're on a mailing list that adds rfc2369 List-foo headers.

exmh nicely adds the List... meny for you.

Now let's say that you forward a mail as a message/rfc822 attachment.

Should the 2369 headers do anything interesting when displaying the
message/rfc822?  My gut feeling is it should do one of:

1) Nothing (the current default)
2) Put up the List... menu (could be funky if the msg is a re-forward
of another msg/822, so there's multiple List-foo headers.
3) Add the entries to the right-mouse list, along with "show full headers"
and "extract into current folder" and stuff like that.

Opinions?
