I like that, provided a changed default :-). I think the
proposed behaviour, while useful for some, is counterintui-
tive. IMHO one doesn't expect marks to change by a simple
copying/moving.

  Especially, since it requires a group change when you want
to archive a mail in a auto-expirable group: Consider moving
a) a mail to be archived and b) a mail to be auto-expired.
With current Gnus setup, you read mail a) and move it, and
read mail b), set the expirable mark and move it. With your
patch, while handling mail b) gets simpler, you would have
to tick mail a), move it, change to the destination group
and mark it as read.
