Sorry, I replied too quickly. It's of course the #'enclose-bounds
property you should use in combination with #'extra-offset. So, in my
reply replace bound-padding with enclose-bounds... enclose-bounds makes
the line shorter AND moves the edge-text along with it. So after you've
made it shorter, you move the entire spanner.

Sure!
