GNU Emacs 18.52, lisp/prolog.el

indent-new-comment-line inserts one space too much, i.e.

%%%  indent-new-comment-line (M-LFD) was called at this point ->
 %%% and the comment continues like this.

(The extra space is removed by reindenting the line with TAB, i.e.
prolog-indent-line.) 

Inserting a test for beginning of line in 'prolog-comment-indent seems
to be sufficient:

--- prolog.el	Thu Sep 21 17:18:41 1989

  		    comment-column)))
  	))
