I was wondering how you fixed it.  That's neat.  Do you need the
--sort-change-0.6?  You probably do, but I don't know what order you end up
with using --apply-change with full history diffs.

Perhaps I should create a --read-zero task.  An empty osm file is often
handy.  It would avoid having to create empty.osm files like that.
