The C standard says that the isxxx() and toxxx() functions are only defined
if their input falls in the domain of unsigned char, or the special case of
-1 ("EOF"). Therefore, all input values to these functions should be cast
(directly or indirectly) to type unsigned char.
This is a good cage cleaner task, and should be repeated periodically.
