More rigidly, it's nice to confirm that it's a diff from the empty blob
and not from some other random blob.

The tests can get access to the correct OID of the empty blob without
hardcoding it either via $(test_oid empty_blob) or just as
$EMPTY_BLOB, however, that's the full length hex string, so you'd
still need to do some tweaking.

If the tests do truly care about these exact objects, then using
"--full-index" would be a good way to compare with $EMPTY_BLOB
and/or $ZERO_OID and such.
