Yes, The inconsistencies from syntax error can be avoided by -t/--test
option.

But, if the iptables-restore used in a rule generation script and it
fails, inconsistencies will occur. So, I think that the iptables-restore
should avoid the inconsistencies even if the wrong rule-set was inputted
at the real run.

Also, I think that the iptables-restore needs rollback capability for the
situation of iptc_commit failure.
