It looks like this docstring needs to be updated.

keyord for list.sort.

Hi Bruno,
Are you testing py3k?  This is what I see:

  Python 3.0a3+ (py3k:61352M, Mar 12 2008, 13:11:35)
[GCC 4.0.1 (Apple Inc. build 5465)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
 >>> [].sort(cmp=lambda x, y: 1)
Traceback (most recent call last):
   File "<stdin>", line 1, in <module>
TypeError: 'cmp' is an invalid keyword argument for this function
 >>>

In listobject.c, in listsort(), at line 1863, we have
the following, which appears to be where "key" and "reverse"
keyword args are supported, but not "cmp".

	static char *kwlist[] = {"key", "reverse", 0};

	assert(self != NULL);
	assert (PyList_Check(self));
	if (args != NULL) {
		if (!PyArg_ParseTupleAndKeywords(args, kwds, "|Oi:sort",
