So, you can pass a temporary to make_filtered_graph? Yeah, that should
work. I'll add an overload.

The intent of the current approach is to keep the cv-qualification of
the graph that's passed in.

  adjacency_list<...> g;

  foo(make_filtered_graph(g, ...)); // filtered_graph of non-const g

  const adjacency_list<...>& gc = g;
  foo(make_filtered_graph(gc, ...)); // filtered_graph of const g
