proposed change: make tcpdump -n and tcpdump -nn behave differently

[Denis Ovsienko <denis () ovsienko info>]

Hello list.

At https://github.com/the-tcpdump-group/tcpdump/pull/702 there is a simple proposed change, which seems to be an 
improvement:
-------------------------
Subject: Introduce -nn option

This changes the semantics on -n option so only namelookups are skipped. Port
numbers *are* translated to their string representations. Option -nn then has
the same semantics as -n had originally.

This is a partial upstreaming of tcpdump-4.9.2-3 used in CentOs 7.5.
-------------------------

If anybody sees how this change isn't an improvement, please make your point on the list.

Thank you.
