py3: remove smartquotes from README They break running setup.py with py3 but only in tests, because in the test environment `locale.getpreferredencoding()` is ANSI_X3.4-1968, so the file is `open()`ed with that as the encoding. An alternative for fixing this would be to make the `open()` call with `encoding='utf-8'` under py3, which would be safe against any future non-ascii in README.
