Auto-save files are local by default, so they have the same problem
(being ignored on other systems).  However, lock files are tiny, while
auto-save files can be arbitrarily big, so from a practical point of
view there's less reason to default lock files to being local.

So I agree that having lock files being remote would be a good default.
