From recently, help(len) gives the wrong signature of len.

Help on built-in function len in module builtins:

len(...)
    len(module, object)
        ^^^^^^^^
    Return the number of items of a sequence or mapping.

I tried to track it down, I think it happened here: http://bugs.python.org/file33655/larry.support.text_signature.on.more.types.6.txt

I realize it was a part of some big fix, so I don't know how easy it is to fix independently. Also, you might think it's not so big an issue. But I teach Python, and my pupils are really confused because of this. Please fix it if anyhow possible. Tnx.
