Sorry, I expressed myself badly.  Yes, of course UNIX (not Unix) has
been a trademark of its owners for decades.  I was referring to the
fact that BSD may no longer be called UNIX, whereas older versions
were.  4.3BSD was definitely UNIX, but 4.4BSD isn't.  That change goes
back to about the Net/2 times, I'd say.

I'm copying this one to chat, since I can imagine that there could be
significant followup.
