14 years later, we still don't know what it's for.
Spotted by the PyPy developers.
Original commit is:
branch: trunk
user: guido
date: Mon Aug 19 21:32:04 1996 +0200
files: Python/getargs.c
description:
[svn r6499] Support for keyword arguments (PyArg_ParseTupleAndKeywords) donated by
Geoff Philbrick <philbric@delphi.hks.com> (slightly changed by me).
Also a little change to make the file acceptable to K&R C compilers
(HPUX, SunOS 4.x).
