Yes, this is a good explanation. Reusing your terms below, --skip-small
controls the algorithm, and --alternate-blocks controls the presentation
layer.

Yes.

This was just brainstorming, though - this might not be the direction we
want to take in this patch. (The right solution might just be to always
use blocks - thereby simplifying the algorithm aspect.)
