Re: ruler-mode.el fix following whitespace cleanup

>From my previous message:

   Never mind, now I understand.  C-M-q and there we go.  Yes, this is a
   real problem.

After all no, if you use ;; does the doubling up not prevent
reindentation?  Which means that ?\ ;; should be safe (or not?).  That
might put the comment in an unconventional place, but it is obvious
why it is where it is, anyway.

But I like the ?\_ suggestion too.  It would not only be clearer but
help prevent all kinds of accidents with accidental tabification.

Sincerely,

Luc.
