Russ Cox c862641ee9 cmd/digraph: only print non-trivial sccs ... In 'digraph sccs', do not print trivial single-node components. This is more useful because it distinguishes nodes with self-loops (printed) from nodes without (not printed). Also remove an unnecessary TODO about map[string]bool vs map[string]struct{}. The savings is at most 5% and if we really cared about storage we would probably not use a map at all.
