On commit, we need to record that outside/ has the new nodeid that we got from the side we merged in. To do that, we need to remember what that nodeid is, from the time of `hg merge` to the time of `hg commit`. That probably means storing the nodeid in the dirstate (like git does), or maybe in the merge state.

  I think neither of them currently contains files outside narrows, so we'd need to extend whichever we decide. It's probably easier to extend the merge state. I'm not sure which I think is cleaner to extend. There's precedent for populating the commit based on the dirstate (index) in git.
