Should this also cover the "POSIX" locale? What about the reference to
"C" in dcigettext?

"POSIX.UTF-8" is not a valid locale string, as far as I can tell, so we
do not have to treat "POSIX" differently in this context. Plain "POSIX"
seems to have been normalized to "C" at this point.

The remaining references allow having different messages for C and
C.UTF-8, maybe with added Unicode punctuation characters. That seems
useful.
Thanks,
Florian
