Summary: dict.popitem documentation should mention empty dict case

Initial Comment:
Currently the documentation in the Python Library
Reference entry for Mapping Types does not mention what
happens when dict.popitem() is called on an empty mapping. 

I think that the documentation should mention that a
KeyError exception is raised. (At least this is what
happens when I try it in the official Python 2.4
release with a dictionary.)

If this omission was intentional to give room for
future implementors of python/mappings I feel that this
should at least be mentioned in the documentation to
remind programmers this behavior is not specified.

I wasn't being very precise when I substituted dict for
mapping types in the summary. I'm so used to thinking of
them interchangeablely. I suppose it might matter though.
