That's because the "buffer copy" also copies the local vars, and indeed
that's where I made a typo.

Yes:

			(push (cons var val) varvals))))
	       varvals)))

should be

			(push (cons var val) varvals)))))
	     varvals))

so that the final `varvals` is outside the `dolist` (it's the thing we
want to return to store it in the outer `varvals` variable).

Sorry 'bout that,
