The problem is that the expiry move is done from a rather low level --
it's actually implemented in `nn*-request-expire-articles', which has
no concept of article marks at all.  So copying over marks would
probably require lots of hacking around.

(Well, I've looked over the code, and it actually wouldn't be all
that difficult.  The most fiddly bit would be to actually copy over
the marks.  Is there a function pair in Gnus that gets/sets article
marks for arbitrary groups?  I can't recall writing such functions,
but perhaps somebody else have?)

Anyway, I've now made `nnmail-expiry-target-group' mark articles as
read when it copies them over, which is simple enough to do.
