You should add the new feature to the manpage.  The extension should
then fail with an appropriate message if the version of the kernel does
not support the option used.

eg. libipt_MARK.c's "parse_v0" accepts --and-mark (introduced in rev1)
like so:

	case '2':
		exit_error(PARAMETER_PROBLEM,
			   "MARK target: kernel too old for --and-mark");

Cheers,
Rusty.
