| If CLASS is actually an object, then also display current values of
that object.

Either the above doesn't make sense as written or `describe-class' doesn't
actually do what the doc says when CLASS _is_ an object.

When a slot has an :allocation :class spec evaluating objects class does not
reveal the value of the class-allocated slot.
