Yep.

Badabing.

I'm planning to add isblank to std::locale (LWG 2019) which will need changes
to all the locale models so while I'm doing that I will overhaul the ieee
locale model (possibly adding a POSIX 2008 version as well, which would be
close to the gnu model) and I'll also address this, so we can handle values
over (1<<15).  Currently that '15' maximum is hardcoded in a few places.
