The spliterator for a collection containing no elements should only be required to support SIZED and need not report any additional required characteristics.

This makes it easier to share a single immutable instance of an empty spliterator for empty collections obtained from Collectionsempty* methods. Since there are no elements it does not matter if additional characteristics are not reported since they would not aid the client to "to control, specialize or simplify computation".

The reporting of SIZED is important since clients can determine if the spliterator is empty.
