dirstate.status: return explicit unknown files even when not asked dirstate.walk will return unknown files that were explicitly requested, even if listunknown is false. There's no point in dropping these files on the floor in dirstate.status. This has no effect on any current callers, because all of them assume the unknown list is empty and ignore it. Future callers may find it useful, though.

shelve: add minimal documentation to all functions There is a lot of functions in this extension. We had a small documentation help people getting started.
