Georg, I hope you don't mind me assigning this to you.  Feel free to
unassign.  A colleague pointed me to section 5.7 in the old ref doc:

http://docs.python.org/ref/shifting.html

It says that shifting operations lose data on overflow.  This info is
outdated based on PEP 237.  I suspect there may be other inaccuracies
related to int overflow.  So the purpose of this bug is to point out the
specific problem as well as to log that we need to find all invalid
references to overflow.

Just jumping in to say the colleague Neal refers to is me, and I'm
interested in the resolution to this bug.  Thanks in advance for your help.

OK, I think I fixed the remaining locations in r63055.
