I remember adding this patch, without it csvkit doesn't build with the
following error:

```

```

I'm not familiar enough with the python build/test process to know for
sure if this is an issue with csvkit or python-slugify. We could just
package the python-text-unidecode package, but AFAIU the
python-unidecode package we already have is equivalent so it should be
OK. But somehow csvkit's check procedure doesn't see that.

Should we keep this patch around? Or maybe somebody has a better idea of
what's going on? I realise now I should have added a comment here :-).

Thanks!
