1. emacs -Q
2. Click mouse-3 over the major mode indicator in the mode line and
select Auto fill from the pop-up menu.
3. Click mouse-1 over "Fill" in the mode line and select "Turn Off[sic]
minor mode" from the pop-up menu.
=> Auto Fill mode remains enabled.
I traced this problem to auto-fill-function from simple.el, which is the
value of cmd in the last when-sexp of popup-menu from mouse.el: since
auto-fill-function is not interactive, (commandp cmd) is nil and the
body of the when-clause, containing a call to cmd, is not evaluated.
But simply making auto-fill-function interactive is not enough, since
auto-fill-function is a no-op. The following redefinition of
auto-fill-function makes step 3 above DTRT, but I suspect it is not the
right fix, since I assume auto-fill-function was meant to be a no-op:
(defun auto-fill-function ()
"Automatically break line at a previous space, in insertion of text."
(interactive)
(auto-fill-mode))
