Obviously good.

I very much like the way this test emulates an operation in a
repository that lack certaion objects so cleanly, and wish we
had used this pattern instead of poking at loose object files
in hundreds of existing tests (#leftoverbits obviously).
It also justifies why a silent "return -1" in the patch is
sufficient ;-)
Thanks.
