Cool!  However, I'm not sure you need the special check to change a
checksum that is genuinely all zeros to all ones.  The risk of rsync
ignoring a read error because the checksum was all zeros is no greater
than the risk of rsync falsely concluding that a file was correctly
reconstructed due to a checksum collision.  Furthermore, files that
checksum to all zeros will inevitably confuse the user's determination
of whether the logged checksum is a bad one.
