Test windows newlines

Fixes the universal newline issue on Issue #57.

```
(Pdb) p fixes == afixes
True
```

Still getting a fatal though, apparently unrelated:

```
c:\github\pep8radius\tests (test_windows_newlines)
λ nosetests --pdb -s test_pep8radius.py
...SSS.fatal: Not a valid object name random_junk_sha
```

`--pdb` and `--pdb-failures` is not dropping me in to debug the fatal.

Sorry for the mess of May stuff in this pull request, I'm not sure how to remove them.  If you know how I should clean up my repository to get rid of the detritus it'd be appreciated.
