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?"
