[Bug libstdc++/34733] numpunct::grouping() doesn't match libc value for Bulgarian (bg_BG) locale

I think the disconnect might be in how each of us is looking at the LC_NUMERIC
data. To me, it's just a bunch of values that are independent of one another.
You, OTOH, seem to view it more as a set of rules described by the data (if
thousands_sep == NUL then grouping doesn't matter).

The reason why I don't look at it that way is because I think the rules for
the interpretation of the data are separate from the data: in C they are
in sprintf and C++ in num_put.

So while I agree that "NUL thousands_sep means no grouping" to stdio and to
iostreams in C++, it's just one possible interpretation of the data for the
specific purposes of the two libraries. There are other possible and equally
valid interpretations/rules that can be drawn from it (e.g., in third party
code).

Finally, I'm not suggesting or even hoping that anything be done about this
in libstdc++ ASAP, or necessarily at any point. I mostly just wanted to make
a record of the issue (whether you consider it valid or not) and get your
perspective on it, that's all :)
