Did you guys happen to read the patch?  It doesn't just silently fix the
behaviour..  now if it reaches that point I believe you'll get back an scp
error.  I don't think you're out of the woods.  So now no data loss, but
the scp will come back with an error..  may take code changes to handle
that still.  Thanks for sharing the thread on this one.

Now, how do I get IBM Bug Proxy to insist that rsync copy operations
fallback to a non-compare method when working on local... I don't think
users expect rsync to go as slow as it does when used on local to local
copies.  Apparently they don't care about my bug reports as much as IBMs.
