I don't understand.  The FE would do this:

    -var-set-child-range 10 20
    -var-list-children

I suppose with the list-children approach we can have resetting be
done like:

    -var-list-children foo -1 -1

Another question is whether changing the visualizer ought to reset the
selected child range.  I'm not sure it matters; I assume a FE will do
this itself.
