This reverts commit 206f9e43e9.
tmac.n contains a comment asking that modified versions not be
distributed. So back out the change which updated '.ux' with
the current trademark owner for "UNIX" so that we can continue
distributing with Guidebook.mn. We'll handle the out of date
trademark issue in another fashion.
The 'roff Guidebook's first reference to UNIX includes a footnote with
the trademark notice. Several subsequent ones do not. I think that's
ok; I think the '.ux' macro even keeps track and only issues it once.
But the extra ones aren't currently using '.ux' and probably should in
order to get the '(tm)' character. I'll leave that for someone else....
The history section mentions quite a few trademarked names. I hope
that the blanket "brand and product names are trademarks or registered
trademarks of their respective holders" is sufficient for them.
so that it will not be included in the diff between
the versions.
Also note that the -ko option in effect for that file
causes it to leave the value at whatever is
checked in from now on.
