Contrary to the docs, auto-fill-mode called programmatically is enabled
with arg 1 and disabled with arg 0.

In which way is that contradicting the docs?  The only case that is
missing is that 'toggle toggles.

Thanks.

If you mean the doc string, then I see nothing there that contradicts
what you say.  (I could agree that the doc string doesn't tell the
whole story, though.)  If you mean some other documentation, please
tell which one.

In the help string, I read:

--
With a prefix argument ARG, enable Auto Fill mode if ARG is
positive, and disable it otherwise.  If called from Lisp, enable
the mode if ARG is omitted or nil.
--

I read it as meaning that

(auto-fill-mode)	; turns the mode on
(auto-fill-mode nil)	; turns the mode on

while everything else turns it off, but

(auto-fill-mode 'off)	; does not turn it off

If the behaviour is the intended one, then probably the doc string
should be amended to add the word "Additionally" at the beginning of the
second sentence, like this:

With a prefix argument ARG, enable Auto Fill mode if ARG is positive,
and disable it otherwise.  Additionally, if called from Lisp, enable the
mode if ARG is omitted or nil.

Surely common sense tells you that is the intended meaning?

There are about 130 instances of this form in Emacs.
There are 4 instances of ", also enable", maybe you prefer that?

Feel feel to correct them all, I guess, if it bothers you that much. :)

See also #13926, and #10754. An automatic solution like 10754 seems best to me.

Well, when reading specifications, I tend to put common sense apart and
look at the literal meaning :)

I think that the way it is worded it may sound ambguous.  in fact, it
has sounded wrong for me.  So, why not add a single word to clarify
things?

>There are about 130 instances of this form in Emacs.
>There are 4 instances of ", also enable", maybe you prefer that?

I suppose you mean something like:

--
With a prefix argument ARG, enable Auto Fill mode if ARG is positive,
and disable it otherwise.  If called from Lisp, also enable the mode if
ARG is omitted or nil.

Yes, maybe it is even clearer and simpler than what I proposed.

>Feel feel to correct them all, I guess, if it bothers you that much. :)

Ok, that amounts to probably never.  In the last years I have barely the
time to report bugs and follow up on them.  Not even always.  Thanks
anyway.

This is a special week, when I have little workload and am trying to
shorten my backlog.  Maybe one day I will find the time and energy to
look at those.  Maybe tomorrow, maybe never, who knows :)
