auto-filling and indent-for-comment.

[Uwe Brauer]

Hello

The following trivial function 
(defun my-add-comment ()				;Version:1.118
  "Combination of linefeed and indent for comment."
  (interactive)							
  (line-feed)
  (indent-for-comment))


Also me to add comments in this form 
(defun my-add-comment ()				;Version:1.118
  "Combination of linefeed and indent for comment."
  (interactive)							
  (line-feed)                    ;this is almost to easy
  (indent-for-comment))          ; to be true


Now I would like that a modification of auto-fill-mode/and or
adaptive-fill would produce this result.

Anybody has an idea?

thanks
