[Python-Dev] Re: [Csv] Minor change to behaviour of csv module

Andrew explains that in the CSV module, escape characters are not
properly removed.

I'm with Magnus on this. No one has 4 year old code using the CSV module.
The existing behavior is just simply WRONG. Sure, of course we should
try to maintain backward compatibility, but surely SOME cases don't
require it, right? Can't we treat this misbehavior as an outright bug?
