Is my understanding of what you're saying correct that there would be 
dead space to the left of the extra top line stuff if line numbers were 
displayed (which is what I want)?

I'll take a look at the logs presently to work out what went in when. My 
older code, relying on stacked synedits, is good for the GTKv1 era.
