Update of /projects/cvsroot/python/dist/src/Python
In directory anthem:/home/bwarsaw/projects/python/Python

Log Message:
eval_code2(): In the extended calling syntax opcodes, you must check

the returned length will be -1.  Make sure this doesn't get obscurred,
and that the bogus length isn't used.
