SF bug #761337: datetime.strftime fails on trivial format string
The interning of short strings violates the refcnt==1 assumption for _PyString_Resize(). A simple fix is to boost the initial value of "totalnew" by 1. Combined with an NULL argument to PyString_FromStringAndSize(), this assures that resulting format string is not interned. This will remain true even if the implementation of PyString_FromStringAndSize() changes because only the uninitialized strings that can be interned are those of zero length. Added a test case.
