FWIW, I agree with the use of unquoted "cdr" in the present case. Especially since the notion of proper list is one that can't be understood before you understand cons/car/cdr, and that there's AFAIK no possible confusion with a normal English word (e.g. I'd be less confident with the use of "car").
