- As Vertical_group_spanner, but keep track of interesting items. If

- gracefully commit suicide. Objective: don't disgrace Lily by
- typesetting empty lines in orchestral scores.

- properties:
-
- items-worth-living -- list of interesting items. If empty in a particular system,
- clear this line
