Only marking *non-read* articles as expired with auto-expire.

[Rob Browning <rlb@cs.utexas.edu>]

Is there a simple way to have gnus not mark read articles as expired
when you're using auto-expire and you re-select the article?

Currently, if I read (hit enter on, or use 'n', or whatever) an
article, it gets marked E, which is fine, but then if I hit 'd' to
mark that as read (so it won't get expired), and later move back to
that article and hit enter to look at it, it gets re-marked as
expired, though I'd prefer it had just stayed "read".

I think I'd like read articles to stay read whenever I just re-visit
them, but I'd still want C-k and friends to mark articles as expired.

Thanks
