Comment (by akaariai):
I have to take back what I said earlier. Unfortunately we have backwards
compatibility requirements for the pre-Lookup classes way of writing
custom lookups. So, we actually don't necessarily have a lookup class at
the point where we want to add the (width IS NULL) condition. So, for now
we have to do this directly in build_filter() method.
