Fix a small bug -- PyDict_SetItem() returns -1 on error, not 0. 

Add check that argument to cc_ass_sub() is a string.  The cache maps
oids to objects, and oids must be strings for now.

Re-indent a bunch of code.

Replace an XXX comment about v->oid with a comment explaining why
getattr is necessary.
