Oh, shoot. I had just copied and pasted the diff output from my terminal, since I wasn't sure if this mailing list would accept file attachments. That was careless of me, since my terminal extended the line off screen. You're right; port 80 is fine. In fact, you might as well get rid of the three prior lines marked "auto detect a port"; that was a remnant from when I was using something other than the limited broadcast address.
I've properly attached the full patch from stable for your convenience.
