Following up from what I said yesterday, I think we need to insert code
to assert that, once all mode adjustments are complete, no mode_size
is still -1. This would go at the end of emit_mode_adjustments.
I guess for now it could be restricted to the modes in adj_nunits
(if that's simpler).
Thanks,
Richard
