.. but it *is* a macro resolving to either PyUnicodeUCS2_GetMax or
PyUnicodeUCS4_GetMax. What is the scenario when may want to change
what PyUnicodeUCS?_GetMax return and have extensions pick up the
change without a recompile? UCS2 case will certainly never change
since it is already 0xFFFF. Is it possible that USC4 will be expanded
beyond 0x10FFFF? Note that we can have both a macro and a function
version. This is fairly standard practice in Python C-API.
