Summary: cPickle/pickle incompatibility

Initial Comment:
Pickling of functions:
pickle.py first tries a save_global.
If that doesn't work, it tries a save_reduce.
This fallback allows to register pickling of local
functions
via copy_reg.

cPickle doesn't do that.
This bug/omission exists since Python 2.3. 

Solution:
A simple patch allows cPickle to fall back to reduce as
well.

Range:
I think this patch should be applied back to Python 2.3.
