Probably nothing in this algorithm; it was only there by extension from the
supposedly generic version we started with.
I guess the algorithm still isn't quite right, since I want to label the
node copies with their total cost from the start. This would require yet
another departure from the supposedly generic form.

Now do you begin to see why a _truly_ generic algorithm could be really
difficult to write?
