Summary: Misuse of strcmp() in -[OC_PythonString __realObject__]

Initial Comment:
Relatively recently, -[OC_PythonString __realObject__] was improved to try to use an encoding which matches the Python default encoding.  Unfortunately, it was done incorrectly.  It uses strcmp() as though it were a strequals() function, but the return value of strcmp() has the opposite logical sense.  It's 0 when the strings are equal and non-zero when they differ.  The result was that it uses UTF-8 when the Python encoding is "ascii" and ASCII otherwise.  (That's actually not a terrible result, since on Mac OS X UTF-8 is almost always the correct encoding to use, even though it's not Python's default encoding.)

Anyway, I'm attaching a patch to correct the logic.
