The test was

;; foo
;;       
;; bar

where comment-only-p would give the wrong results.

Anyway, I think it's ambiguous whether whitespace only should be a
comment or not.  The current algo considers this to be one comment:

;; foo

;; bar

And I think that's correct.  If we consider whitespace lines to not be
comments, this would change how our comment navigation commands work.

So there's some DWIM in this area, but I think how it currently works is
basically the way we want it to work, so I'm closing this bug report.
