Update of /cvsroot/python/python/dist/src/Objects
In directory usw-pr-cvs1:/tmp/cvs-serv17321/Objects

Modified Files:
	listobject.c 
Log Message:
Fix the bug described in

http://mail.python.org/pipermail/python-dev/2002-June/025461.html

with test cases.

Also includes extended slice support for arrays, which I thought I'd 
already checked in but obviously not.
