[Python-Dev] New lines, carriage returns, and Windows

[Guido van Rossum]

[moving to python-3000]

The symmetry isn't as strong as you suggest, but I agree it would be a
useful feature. Would you mind filing a Py3k feature request so we
don't forget?

A proposal for an API given the existing newlines=... parameter
(described in detail in PEP 3116) would be even better.

And a patch would be best, but you know that. :-)
