I am making C-M-j in octave mode do something sensible for breaking
lines, something like:

(defun octave-indent-new-comment-line (&optional soft)
  "Break Octave line at point, continuing comment if within one.
Insert `octave-continuation-string' before breaking the line
unless inside a list.  Signal an error if within a single-quoted
string."
  (interactive)
  (cond
   ((octave-in-comment-p) nil)
   ((eq (octave-in-string-p) ?')
    (error "Cannot split a single-quoted string"))
   ((eq (octave-in-string-p) ?\")
    (insert octave-continuation-string))
   (t
    (delete-horizontal-space)
    (unless (and (cadr (syntax-ppss))
                 (eq (char-after (cadr (syntax-ppss))) ?\())
      (insert " " octave-continuation-string))))
  (indent-new-comment-line soft))


Let me know when you have finalised how double-quoted strings should be
broken.
