&REST lists

I think it is legal for APPLY to pass user-specified list structure to
the function; if so the &REST list should be treated as read-only, as it
well might be.
That doesn't follow. Just because you pass a read-only list to APPLY
doesn't mean that it has to use that same list when it invokes the
function. APPLY could COPY-LIST it. Or in an implementation that uses
stack-consed &REST args the list elements might be copied to the stack.
