The example hook barfs on the initial import. Ideally it should produce a diff from an empty tree, but for now let's stop at squelching the bogus error message. Often an initial import involves tons of badly formatted files from foreign SCM, so not complaining about them like this patch does might actually be a better idea than enforcing the "Perfect Patch" format on them.
