Perfect!

That would be nice, but...

`elisp--local-variables´ doesn't use that built-in any more, it uses
`macroexpand-1` instead, which is implemented in `macroexp.el` :-)

But the problem is that the advice wraps the call within
a `condition-case` and that's inconvenient to do in a way which
doesn't interfere too much with "normal use" (e.g. doesn't hide/catch
errors when we don't want to, and doesn't impose too much of
a performance cost either).

Then again, maybe I'm worrying about nothing.
