I think the csv module was started before universal newline mode was
available.  We allow the user to specify the line terminator, and I suppose
it could be anything, hence binary mode.  We'll have to consider whether
universal newline mode - along with an implicit restriction in possible EOL
sequences - is the way to go.

Thanks for the feedback,
