node: define experimental identifiers for working directory The "ff..." node was introduced at 183965a00c76, and we also need an integer that can be processed in revset. We could use len(repo), but it would be likely to hide possible bugs. Instead, using INT_MAX, we can notice such bugs by IndexError, at the cost of handling non-contiguous revisions.
