Content
Perhaps the 'csv' module should do some sanity checking on the file passed to the reader. The docs recommend that newline='' be used to open the file. Maybe 'csv' could check that and warn if its not the case. I poked around but it seems like io files don't have a handy property to check for that. Further, maybe 'csv' could check if the file is a codecs.StreamReader object. In that case, there is no way to turn off the extra newline characters and so that's probably a bug.
