1. Same setup described in #56592, but additionally set
   nnselect-always-regenerate to t for the groups.
2. Enter group.  Mark an unread article as read.

   (length gnus-newsgroup-selection) => 935
   (car (last (gnus-info-read (gnus-get-info gnus-newsgroup-name))))
       => (930 . 935)

3. Exit group.  Enter group again.

   (length gnus-newsgroup-selection) => 934
   (car (last (gnus-info-read (gnus-get-info gnus-newsgroup-name))))
       => (930 . 935)

4. Attempt to exit group again.  Then, while binding select-reads at the
   beginning of nnselect-push-info, nnselect-categorize signals
   args-out-of-range, because one of the inline functions it calls
   attempts to read the 935th element of gnus-newsgroup-selection.

I believe that the nnselect-always-regenerate branch of
nnselect-get-artlist needs to update the group info, because the
following hack seems to avoid the problem.
