Well, the question then is whether that behaves correctly. Where it would
matter is if the WCO qual contains a SubPlan, because you'd be adding
multiple instances of the subplan to the PlanState's list. I think it's
probably all right, but it might be wise to add a test case where there
is such a subplan.
Spacing and comment wording seem a bit random in this, too.
