Well, yes, close it.

I still think that tcpdump behaviour is wrong, or at
least misleading.  Having to specify -q (quiet?) to
actually get more information (i.e. the port number,
which I expect to be displayed by _default_) is not
intuitive, and it's not documented this way.  This
makes it more difficult to post-process output in
scripts.

But all of that is probably way beyond the scope of
this PR, so please close it.

Best regards
