Let the caller of extendSelectorList know if we extended something. That way, they can avoid an expensive parser call if nothing has changed. The check now is pretty simplistic. It will return false if we didn't do anything in extendSelectorList. We could potentially run the extend algorithm and get the same result and mark that as extendedSomething, but I'd rather not filter out legitimite cases, so let's say conservative.
