hi.
have you established that it's the documentation that is wrong? i.e.
that "urgent" is printed, and not actually "urg"?

It is "urg". The correct diff is this, I think.

The situation is a bit more subtle than that. Just above, the manual
page leads with this header.
The general format of a TCP protocol line is:
src > dst: flags src-os data-seqno ack window urgent options
It is saying there's a section of the line regarding the _window_, then a
section regarding _urgent_, then a section regarding _options_. In the
next paragraph it vaguely describes each of these without getting into
the specifics of the actual printed format (for instance, _window_ is
actually printed as " win %u".
The .Ar above are the "section names" of the line. I think Tim's diff is
right.

I don't agree. Because then "window" needs to be replaced with "win"
as well, and through the entire next paragraph also, and some people
may not win understanding but lose it instead.

i should have added that the macros in this page are poorly used, and
