That's why I said "almost".

I don't think it's a good idea to add this function, for two reasons:

- the unicode API is already big enough, we don't need redundant
  functions with differing refcount behaviours

- the internal wchar_t representation is certainly meant to disappear
  in the long term; adding an API which *relies* on that representation
  is silly, especially after we deliberately deprecated the Py_UNICODE
  APIs
