Summary: cadr and friends not R5RS compliant

Initial Comment:
(cadr '()) => '().  R5RS defines cadr and such to be
compositons of car and cdr, which must report an error
when passed a non-pair.  The cadr-family  procedures
that are "native" do not respect this, and happily
return the empty list when invoked on it.
