    Add some missing casts in ctype functions.
    
    I thought I'd found all of these before, but perhaps a few managed to
    slip in since I last looked. The character argument to the <ctype.h>
    functions must have the value of an unsigned char or EOF; passing an
    ordinary char (unless you know char is unsigned on every platform the
    code will ever go near) risks mistaking '\xFF' for EOF, and causing
    outright undefined behaviour on byte values in the range 80-FE. Never
    do it.
