OTOH you can change ... to something else (but you can't change its
position). Look for selective display in the elisp manual. Or try
this:

(add-hook 'gnus-summary-prepare-hook
	  (lambda () (set-display-table-slot buffer-display-table 
					     'selective-display 
					     (string-to-vector "hit C-M-s for more"))))
