Do you mean when "otherwise" isn't only "we don't add -f now", but also "we accidentally add a -f with different meaning later"? Not sure if there's a real danger of that when we're aware that we want -f with the same meaning as for mirroring. Apart from that, it's HMP, so even in the unlikely case that we mess up, fixing it is still an option. Kevin
