This variable (defconst) doesn't seem to be documented anywhere.

It seems to be used for menus in general; it doesn't seem to be tied to
the menu-bar in any way.  And its only doc is the doc string, which says
only "Separator for menus."  Could it be renamed to remove any mention
of the menu-bar (keeping the old name as alias)?

How is it actually used?  Is it used only in (some?) toolkits?

It's a defconst (why?), so presumably you shouldn't change it.  But
changing it doesn't seem to have any effect anyway, in MS Windows.  If
this is hard-coded then why is it even needed?

It has a doc string, and if you look at its usage, this is all you'll
ever need.

Sorry, this name is with us for too long to rename it now.

Look at menu-bar.el (obviously), it's used all over there.  On all the
toolkits and also in no-toolkit builds.

See above.  If you really want to see the effect of changing it
(why?), I think you will need to rebuild Emacs.

Not a great reason not to rename and alias.

I already looked at all occurrences in the Lisp sources.

AFAICT, _none_ of those occurrences show how it's used
in the sense of explaining its effect.

I'm looking for info about its implementation and what
it actually does - info presumably available in some C
code.  HOW it does what it does.

See also the question about whether it's used only by
toolkits.  In GUI Emacs on MS Windows, for instance,
the effect of a separator is a continuous separator
line, while the effect with `emacs -nw' seems to be a
pair of hyphen chars.

You think so?  How about having the doc specify that,
or whatever the actual behavior is.

FWIW, this bug report is a result of seeing this user
question:

"Is it possible to change the menu separator?"

Why am I not surprised that you don't accept the judgment of the
project maintainers?

Then I really wonder why are you asking all these questions.

You see the effect as soon as you look at the menus which use it.

The HOW is always in the code, so filing a bug about the documentation
is not going to reveal that: we won't describe the implementation in
the documentation.

So I'm closing this bug report.

Each toolkit/UI variant produces its particular visual, but they all
do, and the effect is the same: to visually separate between groups of
menu items.

I see no reason.  You are looking for the kind of internal details
that are always found in the code.

Not every question means something is wrong with our documentation.
Sometimes the answer is "use the source, Luc".

IMHO.

Why am I not surprised that you are personally
hostile, and interpret an opinion as non-acceptance
of a decision?

Can we not politely agree to disagree about what
should be done, without your going off again on
your claims of insubordination?

You expressed your opinion, heard is rejection, and you keep arguing.
Are you aware that every one of your messages with repetitive
disagreements means another message I need to read and consider?  Do
you think I have lots of free time for doing that?

> Can we not politely agree to disagree about what
> should be done

We can, but one message from each side should be enough for that.
There should be no need for "I heard you, but I still disagree".  It's
a waste of time and energy.

You expressed your opinion, heard its rejection, but you keep arguing.
That generates more messages than necessary and increase the workload
for no good reason, while telling nothing new.  Why increase the noise
level here?

We can, but one message from each side should be enough for that.
There should be no need for "I heard you, but I still disagree".  It's
