Sure -- if you think that's better. My reason for doing it this way: if
someone later improves density() to work for multigraphs, adjacency_matrix
will then automatically use the improved code. (I imagine someone might
improve density() but not think to look at adjacency_matrix.) And trying
density() probably doesn't take much time.
Do you still prefer to test if it's a multigraph, rather than catch the
exception? If so, I'm happy to change it.
