Sorry if it's already discussed, but what's the benefit of `cmdstate`
not being a plain dict?

I think plain load/save functions are much simpler than a dict-like object
backed by file, i.e.

  state = statemod.load(repo, fname)
  state = {'version': 1, 'nodes': nodelines}
  statemod.save(repo, fname, state)

(statemod.load/save could be a class for serialization/deserialization)

The state dict would be wrapped anyway depending on application logic.
If we can find out a common behavior between "state"s, we can extract it to a 
state class,
but that will still be separated from the storage format.
