After a bit more thought, I'm not even sure of the definition of a
dead end --- is a road that leads into a closed tree (or other graph)
of roads and dead end? It does lead to other roads, but you can't get
out onto the wider road network without coming back along the same one
again. For example, is
http://www.openstreetmap.org/browse/way/4678941 a dead end?
