Summary: Cannot retrieve name of super object

Initial Comment:
I see that in Python 2.3b1 many problems of super
have been fixed, but this one is still there:
I cannot retrieve the __name__ of a super object.
This generates problems with pydoc, for instance:

>>> class C(B):
...     sup=super(B)
>>> help(C)
Traceback (most recent call last):
  File "<stdin>", line 1, in ?
  File "/usr/local/lib/python2.3/site.py", line 293, in
__call__
    return pydoc.help(*args, **kwds)
  File "/usr/local/lib/python2.3/pydoc.py", line 1539,
in __call__
    self.help(request)
  File "/usr/local/lib/python2.3/pydoc.py", line 1575,
in help
    else: doc(request, 'Help on %s:')
  File "/usr/local/lib/python2.3/pydoc.py", line 1368,
in doc
    pager(title % desc + '\n\n' + text.document(object,
name))
  File "/usr/local/lib/python2.3/pydoc.py", line 279,
in document
    if inspect.isclass(object): return
self.docclass(*args)
  File "/usr/local/lib/python2.3/pydoc.py", line 1122,
in docclass
    lambda t: t[1] == 'method')
  File "/usr/local/lib/python2.3/pydoc.py", line 1057,
in spill
    name, mod, object))
  File "/usr/local/lib/python2.3/pydoc.py", line 280,
in document
    if inspect.isroutine(object): return
self.docroutine(*args)
  File "/usr/local/lib/python2.3/pydoc.py", line 1145,
in docroutine
    realname = object.__name__
AttributeError: 'super' object has no attribute
'__name__'

P.S. I seem to remember I already submitted this
bug (or feature request, as you wish ;) but I don't
find it in bugtracker and I had no feedback; maybe
it wasn't sent at all due to some connection problem.
If not, please accept my apologies.

The patch was applied.  It's possible one of the subsequent 
patches broke it.

Opening patch again.

I've just checked today with Python 2.3 (pydoc
revision 1.86):

class B(object):
    pass

class C(B):
    sup=super(B)

help(C)

still gives the same error!

What happened? Did you forgot to add the patch to 
the standard distribution? The bug is not close!

Patched pydoc (revision 1.84) to try an object as "other" if what 
inspect identifies it as does not work based on its assumptions.

The issue is inspect.isroutine is saying that the instance is a 
callable object since it is also a non-data descriptor.
