``auxIndexes.get(tag)`` will return null if ``tag`` has no auxiliary
indexes defined - which is not an unusual case.
As I look at ``Util.getAuxIndexes`` I unnecessarily return an empty list
that then does no work in the guarded ``for`` loop. I'm changing to ``null`` in
the case of a ``null`` or empty ``tag``.
