>Description:
We have

.St -isoC-2011

for C11, and mdoc(7) documents

.St -isoC-2018

but doesn't say what it's for (is it C17, i.e., ISO/IEC 9899:2018?).

I can't find anything in mdoc(7) for C23 or any C++ standard versions.
>How-To-Repeat:
Write a man page that needs to cite C23 and C++20 (or any of various other C++ standards).
>Fix:
Yes, please!
