[docs] [issue19163] PyString_Format with dict

[hiroaki itoh]

New submission from hiroaki itoh:

http://docs.python.org/2.7/c-api/string.html#PyString_Format

The documents says `The args argument must be a tuple.',
But if format is like '%(key)s', PyString_Format claims
args must be mapping protocol.
(At least 2.7.3.)
