locking: take the `wlock` for the full `hg add` duration Otherwise, there is a race condition window between the time we resolve the file to add with the matcher and the time we lock the repo and modify the dirstate. For example, the working copy might have been updated away, or purged, and the matched files would no longer be correct.
