First merge from the trunk straight into the py3k branch. I'm not

using the message generated by svnmerge, because it contains a lot of
stuff about the Doc tree, which I'm not merging this time due to the
way the Doc tree was initially added.  I am however adding roman.py
which was added later to Doc/tools.  I'll try to diff the two Doc
trees separately to see if there's stuff I missed.
