Summary: textwrap ignoring fix_sentence_endings for single lines

Initial Comment:
>>> import textwrap
>>> t=textwrap.
TextWrapper(fix_sentence_endings=True)
>>> print t.fill("A short line. Note the single space.")
A short line. Note the single space.

TextWrapper.wrap() is implemented as:

    def wrap(self, text):
        text = self._munge_whitespace(text)
        indent = self.initial_indent
        # *** Next line seems to be the bug ***
        if len(text) + len(indent) <= self.width:
            return [indent + text]
        chunks = self._split(text)
        if self.fix_sentence_endings:
            self._fix_sentence_endings(chunks)
        return self._wrap_chunks(chunks)

(if sf breaks the indentation, check the actual source!)

That early-return "if" clause seems to be an incorrect 
optimisation which skips fix_sentence_endings.  
Commenting it out seems to fix the problem.
