I have

(defvar octave-comment-start-skip "\\(^\\|\\S<\\)\\(?:%!\\|\\s<+\\)\\s-*"
  "Octave-specific `comment-start-skip' (which see).")

and this could find "#abc" as comment start where BEG is outside of
strings and comments but END is in a string.

Maybe this is due to setting octave-comment-start-skip incorrectly.

I looked at comment-normalize-vars and see it uses:

  \\(\\(^\\|[^\\\n]\\)\\(\\\\\\\\\\)*\\)

as anchor but I don't understand fully.
