I am running gnus master from within the last week or so.

I use topics, and on some topics have properties (auto-expire t).  This
used to be inherited by all the groups in the topic (IMAP folders that
get mailinglist mail delivered into them).  But now, this isn't
happening, and the messages are marked R but not E, and on re-entry O
(just like they should be if auto-expire were not enabled).

Is this intentional, or a bug?
