/* Taking advantage of the C99 mutual-exclusion guarantees for the various

 * (w)chars, we can place each in one of the following mutually-exlusive
 * subsets.  Since there are less than 16, we can store the data for
 * each (w)chars in a nibble. In contrast, glibc uses an unsigned int
 * per (w)char, with one bit flag for each is* type.  While this allows
 * a simple '&' operation to determine the type vs. a range test and a
 * little special handling for the "blank" and "xdigit" types in my
 * approach, it also uses 8 times the space for the tables on the typical
 * 32-bit archs we supported.*/
