[New-bugs-announce] [issue8850] Remove "w" format of PyParse_ParseTuple()

[STINNER Victor]

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

"w" format is dangerous because it doesn't give the size of the buffer: the caller may write outside the buffer (buffer overflow).

"w*" and "w#" formats are fine.

It looks like "w" format is not used in trunk nor py3k (only w# and w*).
