It's one of those "technical" errors that really isn't an error (from
Python).  On the other hand, opening a file in text mode will cause
real data damage to binary files on Windows.  Let some
platform-specific library for that platform preserve it, if it cares
to.

I see no point in keeping this distinction in Python, even for those
platforms bone-headed enough to preserve it.  And the default
certainly shouldn't be to the mode which loses data.
