Reformat ctype.c

Browse Source 
Enhance the readability of ctype.c by using an enum instead of macros
to initialize the character class table.  This allows the use of a single
letter to mark a char, making the table fit within 80 columns.

Also list the index of the last entry in each row in the following comment.
