Subject: bug#46193: Enabling Auto Fill mode
Date: Mon, 1 Feb 2021 12:59:25 +0100

I have now made the following function.  Would I better make the
functionality to be buffer-local?

(defvar dfv-break-long-lines-state nil)

(defun cycle-break-long-lines-din ()
  "Breaks long lines using auto-fill tool."
  (interactive)
  ;;
  (pcase dfv-break-long-lines-state
    ;;
    (1 (setq fill-column 72)
       (setq comment-auto-fill-only-comments t)
       (auto-fill-mode)
       (message "%s" "Enable: Break only comments")
       (setq dfv-break-long-lines-state 2))
    ;;
    (2 (setq comment-auto-fill-only-comments nil)
       (message "%s" "Enable: Break all long lines")
       (setq dfv-break-long-lines-state 1))
    ;;
    (_ (setq comment-auto-fill-only-comments nil)
       (auto-fill-mode 0)
       (message "%s" "Disable: Break long lines")
       (setq dfv-break-long-lines-state 0)) ))

(defun break-long-lines-din ()
  "Breaks long lines using auto-fill."
  (setq dfv-break-long-lines-state 1)
  (cycle-break-long-lines-din))
