     c-comment-edit is a command that copies a C comment into a
     temporary buffer for editing under a more suitable major mode
     (usually text-mode).
  
  i find it simpler to bind a key to the following:

(defvar fill nil)
(defun my-auto-fill-mode ()
  "Toggles auto-fill-mode and performs other actions as necessary."
  (interactive)
  (make-variable-buffer-local 'fill)
  (setq fill
	(cond ((null fill)
	       (auto-fill-mode 1)
       	       (set-fill-prefix))
	      (t
	       (auto-fill-mode -1)
	       (save-excursion (beginning-of-line) (set-fill-prefix))
	       nil)))
  (update-mode-line))

  this toggles auto-fill mode and sets or cancels the fill prefix,
  thus you have to have the cursor in the right place before executing
  this. 

  note that the default behavior of M-q is to convert:

	/*
	 * stuff
	 */

  to

	/* stuff
	 */

  so i added the following to my c-mode-hook:

	(setq paragraph-separate (concat paragraph-separate "\\|^[ \t]*/\\*$"))
  
  enjoy!
