Moving the content of comment line of these two rules to option name is more desirable.  A patch by you will be even nicer.

I thought the udp port 500 and ip proto esp itself are quite self-evident, not to mention the kind of redundant comment line.  That's why I closed the task as I thought it was not a "have no documentation" issue...

Please propose a patch to the mailing list and add a line in the commit message body that reads "Fixes FS#640".  But there is no need to re-open this task and close it later, is there?
