Actually, I'd just been working on this myself. I think the cleanest
solution will be to get rid of the duplicative logic by making
predtest.c use get_op_btree_interpretation(). That will require
changing get_op_btree_interpretation() so it can return amoplefttype
and amoprighttype too, but given the small number of callers, an API
change for it doesn't seem like a problem.
