[PATCH] Skip writing out sha1 files for objects in packed git.
Now, there's still a misfeature there, which is that when you create a new object, it doesn't check whether that object already exists in the pack-file, so you'll end up with a few recent objects that you really don't need (notably tree objects), and this patch fixes it.
