The reason for returning an empty string for "C" and "POSIX" is the

I'm not sure why, or if that really makes sense.
Peter E, do you have any thoughts on this question?
Doesn't make sense to me either.
We need to handle the various combinations of null and non-null stored
and actual versions, which we do, but that only applies within a given
collcollate. I don't think we need the property that that comment calls
for.
