There are several points here, perhaps we are both missing some of
them.

The problem that I can see (and I believe to be a bug) is:

The function bound to M-g claims to be gnus-group-get-new-news-this-group

-------------------- C-h k M-g --------------------
M-g runs the command gnus-group-get-new-news-this-group
   which is an interactive compiled Lisp function in `gnus-group'.
(gnus-group-get-new-news-this-group &optional N DONT-SCAN)
-------------------- C-h k M-g --------------------

Pressing M-g seems to do the same thing as the function
gnus-topic-get-new-news-this-topic and not the function
gnus-group-get-new-news-this-group.


Why does pressing the key invoke a different function from that
reported by C-h k M-g or C-h b ?  If it reported the correct function
then I would not have had the problem.  This makes it a bug.
