ipt-restore fails to parse the ipt-save output:
zmatches -m rateest --rateest RE1 --rateest-pps --rateest-lt 5
(should be "--rateest-pps 5 --rateest-lt").  Also, the "delta" option
was never shown in -save output, but twice in some cases when using
"iptables -L".

Also, the "b/pps1" option must be shown when "delta" option is used with
relative mode.

Applied, thanks.

iptables release will follow-up soon, including this fix.
