- Added tests for empty and zero-byte strings. Wine passes these tests, sort of.
- Check that the returned string is correct.
- All known Windows versions implement RegQueryValueExA(), so complain if it is not implemented.
- Only allow the Win9x quirks for the Ansi version.
- Query the name2A/W value for the string2A/W tests!
- The test_hkey_main_Value_A/W() functions were doing a sizeof() on the string parameter to compute the string's full size!
- We must reset GLE before each test, otherwise Win9x skips all but the first test.
