It's simply not safe to share objects between repos when we remove objects in the seed repo (which happens automatically behind the scenes when git GCs). This is documented in the git-clone man page. Changing this will increase disk usage some, but that's something we just have to live with.

The filename here was based on the seed repo (which usually has a .git suffix) instead of the scratch repo that we are copying. That didn't really make sense.
