Summary: PEP 341 - Unification of try/except and try/finally

Initial Comment:
Attached is a patch implementing PEP 341 against HEAD
in subversion.

It includes the following changes:
1. Grammar/Grammar updated as per the PEP
2. Python/ast.c wraps try/except blocks inside
try/finally blocks if it detects the extended syntax.

This patch is based heavily upon suggestions by Nick
Coghlan on python-dev.

I'm pretty sure this patch causes this problem:

python: Objects/frameobject.c:187: frame_setlineno:
Assertion `blockstack_top > 0' failed.

I'm not sure if it's just my hacked up version or the
original.  Thomas, can you test your version?

Updated patch to correct memory leaks.  Put everything in
one file.  Works for me.

There needs to be doc changes done too.
