Just to clarify, I use `M-g' in the Group buffer, but looking at the
code I think using it in the Summary buffer does the same thing.

Aside:  While looking at the code, I think I noticed an error in the doc
string of the function that ends up getting called:

  (defun gnus-group-get-new-news-this-group (&optional n dont-scan)
    "Check for newly arrived news in the current group (and the N-1 next groups).
  The difference between N and the number of newsgroup checked is returned.
  If N is negative, this group and the N-1 previous groups will be checked.
  If DONT-SCAN is non-nil, scan non-activated groups as well."

I think the description of DONT-SCAN is inverted (as its name suggests).
It should say:

  If DONT-SCAN is nil, scan non-activated groups as well.

Or

  If DONT-SCAN is non-nil, then non-activated groups are not scanned.
