Does 'r' not use universal newlines on unix? If not, why not? The only
purpose seems to be to allow people to write bad programs and have them
work on unix. It makes even less sense in python 3 where opening a file
in text mode results in a TextIOWrapper with utf-8 encoding, and
therefore can't be used on arbitrary binary files.
