Summary: Docstring for codecs.lookup is incorrect

Initial Comment:
The docstring for codecs.lookup states that this function returns a tuple of functions. I understand this was correct in Python 2.4, but in Python 2.5 this function returns a CodecInfo object, as described in the docs:

http://docs.python.org/lib/module-codecs.html

I've got Python 2.5.1.

CodecInfo objects *are* tuples for backwards compatibility reasons. Also
it's still possible that codecs.lookup() returns a real tuple (however all
standard encoding go through encodings.search_function() so if
codec.getregentry() returns a real tuple this gets upgraded to a CodecInfo
object.)

I've changed the docstring in r56456, so that it mentions both tuples and
CodecInfo objects.
