Package: Emacs
Version: 29.0.50


Alan's symbols-with-pos has introduced a backward incompatible change to
`macroexp-warn-and-return` by adding a new *first* argument `arg`.

The patch below changes that so the new argument comes last (and is
optional).  Alan argued it's preferable for this arg to come first and
the function was new in Emacs-28 so it's OK to break compatibility.

The patch below shows that indeed the arg is almost always
desirable/needed to get the right position information (the default
behavior when the arg is absent is not as good), so it's kind of pain
having it as last arg.  And I'm not super happy with the long list of
args of this function.

But these arguments don't seem strong enough to justify
breaking compatibility, hence the patch below.

Any objection?
