Eliminate test from generated cp macros

Sayeth Karl:
In the _cp macros, the final test can be simplified:

/*** GENERATED CODE ***/
#define is_VERTWS_cp(cp)     \
( ( 0x0A <= cp && cp <= 0x0D ) || ( 0x0D < cp &&     \
( 0x85 == cp || ( 0x85 < cp &&     \
( 0x2028 == cp || ( 0x2028 < cp &&     \
0x2029 == cp ) ) ) ) ) )

That 0x2028 < cp can be omitted and it will still mean the same thing.

And So Be It.
