There are two points of view: the "normal" user is confused if some indexes
show up the number of indexed objects and others show the size of the index
within the same column. This should be consistent. If would prefer the
of indexed objects within the default ZMI view and put index specific size
information into their own default view.

Yes, but DateRangeIndexes overwrite index_object() so that a change
of UnIndex itself would not harm.

"None" could be a problem with other indexes...at least there should be
a unique marker saying: I have nothing of interest to be indexed....
