[Python-3000] UPDATED: PEP 3138- String representation in Python3000

[Terry Reedy]

|
| - Add ``isprintable()`` method to the string type. ``str.isprintable()``
|  return True if ``repr()`` should escape the characters in the string,
|  False otherwise.

Is not this backwards?  Isprintable to me mean should *not* escape.
