In CC Mode modes, a typical value for comment-start-skip is: "\\(//+\\|/\\*+\\)\\s *" . This is erroneous, since it includes regexp grouping parentheses, yet the comment being matched doesn't start at (match-end 1), contravening the definition of comment-start-skip. This mistake is likely to lead to errors in filling, etc. The same bug is present in js-mode. -- Alan Mackenzie (Nuremberg, Germany).
