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.

Andrew Cohen sent me the following fix. I've asked him whether he
thinks this is safe enough for emacs-29.

Just to update this bug, I've been in touch with Andrew recently and he
has sent some improved versions of the fix (many thanks again), but
there are some residual bugs he's still working out before I can do some
final testing.
The final patch will very likely be too large for Emacs 29.
