* - isprint() declaration in ctype.h incorrectly uses _B.
* _B means "isprint but !isgraph", not "isblank" with the
* declaration.
* - _X and _RUNETYPE_X have negligible difference in meaning.
* - we don't set digit value, fearing that it would be
* too much of hardcoding. we may need to revisit it.
