Our repos can scale up to GBytes, so that maybe too expensive to implement.

One concern I'd have is whether -r option would miss some branches that would
result in failure when unbundling on remote repo. Perhaps some kind of
changeset info can be generated from the destination repo, which can be used by
bundle in searching for the deltas? I think darcs is using some kind of context
