[Python-checkins] python/dist/src/Lib pickle.py,1.107,1.108

[gvanrossum@users.sourceforge.net]

Update of /cvsroot/python/python/dist/src/Lib
In directory sc8-pr-cvs1:/tmp/cvs-serv18102

Modified Files:
	pickle.py 
Log Message:
Add a few comments.  Change the way the protocol is checked (it must
be one of 0, 1 or 2).

I should note that the previous checkin also added NEWOBJ support to
the unpickler -- but there's nothing yet that generates this.
