FYI,
I've just comitted a patch which adds the concept of 'null vertex' to BGL. If
'G' is a graph type, then

    graph_traits<G>::null_vertex()

will return vertex_descriptor which does not refer to any vertex. Of course,
that value is never returned by add_vertex.

I found this concept usefull in some code of mine, and I recall somebody asked
for it long time ago.
