Comment (by ncohen):
> So vertices at exactly the limit distance should be handled differently.
They must be on different list, from where they will be moved to "normal"
`already_seen` list if they are re-discovered by smaller distance.
That's going too far. I don't think that we need to 'fix' that, it
probably shouldn't even exist. What you want to use in this case is a BFS.
Or, actually, `Graph.shortest_path_lengths` (whose name is awful).
