If not in prefix mode, all of reader must be consumed; otherwise, the consumed portion
is the prefix and any following keys with the same prefix are ignored.

The bounds are consistent with the reversed ordering (i.e., reversed if reverse is true)
and have already been range-checked against this instance's bounds.createSubSet in class AbstractKVNavigableSet<byte[]>newReversed - whether the new set's ordering should be reversed (implies newBounds are also inverted,
