If the UDP query returns TC=1 DiG retries with TCP. I want to see the

The "tell" is that on the footer SERVER line it reports the protocol.
Note that in the first case it's TCP, even though +notcp was specified.
(The MSG SIZE is also a clue.)
Searching the intertubes wasn't much help. When I tried to search the
list archives I got a Gateway Timeout. :-( Anyway, it's been a minor
personal annoyance for a while; hopefully this helps somebody else with
a problem they didn't know they had.
If you have a specific proposal for docs we would be happy to improve
the dig man page.
