Is there a way to automatically cut all long lines

If I wanted to do it I would write a script in Emacs. (Sorry for unhelpful answer, but the other answers were also unhelpful...) I use `auto-fill-mode' in Emacs: when I insert a space beyond a given column, it automatically breaks the line at a previous space.
