Code review comment for lp:~songofacandy/bzr/i18n-utextwrap

Okay, nearly there. Two tests from textwrapper that use `fix_sentence_endings=True` fail because of this code in the textwrap module which puts bytestrings in the chunks list:

    if chunks[i+1] == " " and[i]):
        chunks[i+1] = " "

Resulting in errors like:

Traceback (most recent call last):
  File "...\lib\test\", line 102, in test_fix_sentence_endings
    self.check(wrapper.wrap(text), expect)
  File "...\i18n-utextwrap\bzrlib\", line 216, in wrap
    return textwrap.TextWrapper.wrap(self, unicode(text))
  File "...\lib\", line 321, in wrap
    return self._wrap_chunks(chunks)

TypeError: must be unicode, not str

Annoying. That option is pretty bogus anyway, I'd not mind just not supporting it. Otherwise _fix_sentence_endings needs overriding so it doesn't mix up types in the chunks list.
