Hit send accidentally. :( Dictionary sorting rules generally skip spaces
in first pass comparisons. If you're expecting byte order sorting, you'll
want "C" locale. We currently use the system locales for sorting, so if
you want something which say uses non-byte order sorting but also doesn't
skip spaces, you'd need such a locale definition for the system.
