* General tests for wcsncasecmp(). Test to make sure that the following are
* true:
*
* o Two identical strings are equal
* o Two strings with the same contents are equal
* o Case insensitive in ASCII works
* o Basic cases where strings aren't equal
* o An ASCII string that would compare greater due to case is properly less
* o Comparing with zero characters succeeds even if different strings
* o Characters in a locale / language that don't have a notion of case are
* consistent
