[New-bugs-announce] [issue9184] open() doc: default value for buffering is -1, not None

[STINNER Victor]

New submission from STINNER Victor <victor.stinner at haypocalc.com>:

Examples:
 * open(filename) works
 * open(filename, buffering=-1) works
 * open(filename, buffering=None) fails

In the code:
 * _pyio.open(): default value is -1, type is int, no default value in the docstring
 * _io.open(): default value is not specified (C function), type is int, default value in the docstring is None

In the doc:
 * open() default value is None

The default value should be -1 everywhere. None is rejected by io.open (_io) and _pyio.open.

Attached patch fixes _io.open() docstring Python documentation.
