Note that the current CSV parser in _csv.c doesn't require the line terminator, it eats up \r and \n where necessary. See: https://github.com/python/cpython/blob/fd512d76456b65c529a5bc58d8cfe73e4a10de7a/Modules/_csv.c#L752 This is why the line terminator isn't detected and doesn't need to be detected. Also, files that use the \r line terminator exist and are parsed correctly at the moment. See for example: https://raw.githubusercontent.com/hadley/data-fuel-economy/master/1998-2008/2008.csv
