The --suffix-dels option is specific to the backup-dir-dels patch.  I
can see how you would get the error if the local rsync contains this
patch and the remote one doesn't.  The patch has a compatibility
problem: if you specify a non-default --suffix to the client, it passes
both --suffix and --suffix-dels to the server, even though they have the
same value.  Get a local rsync that doesn't contain the patch and the
problem should go away.
