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.
