Log Message:
SF bug 693121:  Set == non-Set is a TypeError.
Allow mixed-type __eq__ and __ne__ for Set objects.  This is messier than
I'd like because Set *also* implements __cmp__.  I know of one glitch now:
cmp(s, t) returns 0 now when s and t are both Sets and s == t, despite
that Set.__cmp__ unconditionally raises TypeError (and by intent).  The
rub is that __eq__ gets tried first, and the x.__eq__(y) True result
convinces Python that cmp(x, y) is 0 without even calling Set.__cmp__.

+ - sets.Set objects now support mixed-type __eq__ and __ne__, instead
+   of raising TypeError.  If x is a Set object and y is a non-Set object,
+   x == y is False, and x != y is True.  This is akin to the change made
+   for mixed-type comparisons of datetime objects in 2.3a2; more info
+   about the rationale is in the NEWS entry for that.  See also SF bug
+   report <http://www.python.org/sf/693121>.

  - os.listdir() now returns Unicode strings on platforms that set
    Py_FileSystemDefaultEncoding, for file names that are not representable
