I don't think we do.

Grepping for rsync in t/, it is mentioned in three places:

  1. In t1509, we use it, but that test script does not run unless you
     set a bunch of environment variables to enable it.

  2. In a sample patch for t4100. Obviously this one doesn't execute. :)

  3. In t5500, to test "rsync:" protocol supported. This is behind a
     check that we can run rsync at all (though it does not properly use
     prereqs or use the normal "skip" procedure).

I was assuming that the "-P" in the original had some purpose. My "cp -r" does not seem to dereference symlinks, but maybe there is something I am missing.
