I'm happy with the change. The original intention of the comment was to 
make sure that non-involved ports were still being allowed, and that 
there were no side effects. The comment change somewhat becomes 
redundant as it's repeating the subsequent message. So if it were to 
stay as proposed, I guess it'd drop it altogether.
