I'm not against anything in principle here, but I'd just like to point out two
things:

1. Changing line break semantics would break compatibility with the current
behaviour, and it would also diverge from what the `newline` parameter
specifies; this may be annoying if, for example, the TextIOWrapper class is used
to parse some network protocols with a rigorous line ending definition

2. It would be useful to have some input by the original designers of the IO
library (the PEP lists Guido, Daniel Stutzbach and Mike Verdone, but I suppose
other people were involved)

Antoine.
