TEST_CTYPE_FUNC defines a function for testing a character classifier,
TEST_CHAR_CLASS calls it, causing the class name to be mentioned twice.
Avoid the need to define a class-specific function by letting
TEST_CHAR_CLASS do all the work. This is done by using the internal
functions test__run_begin() and test__run_end(), but they do exist to be
used in test macros after all.
Alternatively we could unroll the loop to provide a very long expression
that tests all 256 characters and EOF and hand that to TEST, but that
seems awkward and hard to read.
No change of behavior or output intended.
