[Python-Dev] check for PyUnicode_READY look backwards

Hi,

with the new Unicode API, there are many checks like:
+        if (PyUnicode_READY(*filename))
+            goto handle_error;

Every time I read it, I get it wrong:
   "If filename is ready, then fail"
then I have to remember that the function returns either 0 or -1.

I'd prefer it was written :
       if (PyUnicode_READY(*filename) < 0)
because "< 0" clearly indicates an error condition.
That's how all calls to PyType_Ready are written, for example.

Am I the only one to be distracted by this idiom?
