While the docs don't currently say anything about it, all the
examples at [1] use 'rb' or 'wb' when opening the file. I've long
wondered about that. Especially as I've passed non-file objects like
lists/iterators to the csv.reader/csv.DictReader and had them work
just fine (and would be a little perturbed if they broke).
