Log message:
Change the rendering of the .Ux macro from "UNIX" to "Unix",
purely for compatibility with groff 1.23.
Not a big deal because this macro is deprecated anyway.

The decision to change this was made in groff because two AT&T
Bell Labs veterans, Doug McIlroy and Meg McRoberts, recalled that
"fairly early on, we in the Unix lab began to treat Unix as a proper
noun, but the lawyers had trademarked the uppercase name and got
their way in many publications."

This cange corresponds to groff commit 8dcc3aad gbranden@ Sep 7, 2022
[mdoc]: Render `Ux` macro as "Unix", in mixed case.
