Doesn't this mean there's an inconsistency?  If leaving some
candidates unranked is shorthand for ranking them equally last,
shouldn't the truncated ballot be divided among all the unranked
when it's time to transfer it?

We've been using examples where we say {Nader,Clinton,Dole} is
equivalent to {Nader,Clinton} in a 3-candidate race.  But these 
two ballots would transfer differently.  I guess this means that 
what's shorthand in one system (single-winner) isn't shorthand in 
another (multiwinner).
