I had time to look into this.  The ones that go wrong are where there
is 'O' on the left beginning with 1, and 'N' on the right.
As in your example above.

It turns out that using -1 as the default value of getRightStart()
is required or else the value of zero must be treated specially
in equalizeBases() by adding 'if (right.targetStart == 0) return false;'
