[PATCH 3/3] t-ctype: do one test per class and char

["René Scharfe" <l.s.r@web.de>]

Simplify TEST_CHAR_CLASS by using TEST for each character separately.
This increases the number of tests to 3598, but avoids the need for
using internal functions and test_msg() for custom messages.  The
resulting macro has minimal test setup overhead.
