The behavior for pointer-params isn't changed. Only non-pointer params
will then accept the additional is_null argument.

If I'm not much mistaken this is not actually possible. NULL is
interpreted by PHP as a zero-y value. So the variable will be just set
to 0 and you have no way to discern a real 0 and NULL.
