Could someone tell me how to set the maximum number of characters per line

I cannot tell you how but as almost anything in Emacs is tweakable it
would certainly be possible to hook-on a function that after each
keyboard press checked if the current column was greater then a
certain number, and if it was, BEEP at the user. Would be very
annoying though... :)

(defun annoy ()
  (if (>= (current-column) 70)
      (beep t)))

(add-hook 'post-command-hook 'annoy)
