Re: How to straighten up group unread numbers

[Steinar Bang <sb@dod.no>]

One approach I've thought about:
 - have a loop that goes through all interesting groups (in my case all
   nnimap, and gmane nntp groups), and for each group
  - Open the group, and loop through and read all unread articles
  - Loop through the recently visited articles, and all articles not
    marked as expired will be marked as unread
  - exit the group

This should:
 - Correct the read count (for nnimap this would be articles read by a
   different gnus, which is handled just by visiting the group, and
   articles that are permanently deleted, which appear as expired after
   an attempted read.  For gmane nntp groups, just visiting the group
   will remove the articles crossposted to gmane.spam.detected (because
   I score them down), and reading each article will remove those
   articles reported as spam)
 - Cache all articles in agent (if that actually works for me now)

Note that just visiting each group will handle everything except the
expired articles (permanently deleted IMAP articles, and reported spam
in gmane), and would be a lot simpler.

Perhaps that could be a first iteration?  The visiting of the
interesting group logic, would be the same.
