Thanks. But before I do the rewrite, let me add a unit test first.

It's a bit tricky only on musl libc, NetBSD, and OpenBSD. Other
than that, there's a test failure on Android 4.3, where
  - setlocale (category, NULL) always returns NULL.
  - hard_locale of the initial locale returns true, but should be false.
