digraph: refactor somepath to print an adjacency list

Refactors somepath to print an adjacency list from "from" to "to", instead of
just the nodes. This allows other tools like modgraphviz to print the subgraph.

This is a breaking change. The previous behavior returned vertices; now it
returns edges. If you relied on the previous behavior, use:

    my-application | digraph somepath <from> <to> | digraph nodes
