OK. Attached are two patches and a test case. The patches are two
alternate methods of approaching the problem.
Keep a staff alive with multiple layers
---------------------------------------
This changes the remove-layer property to number-or-pair? such that a
list of values can be specified. The layer will remain alive with any
other layer whose remove-layer value is in the list.
Keep a staff alive until it is alone in the group
-------------------------------------------------
This patch uses a new boolean property remove-orphan which keeps the
staff alive while any other is alive.
The list approach is a little fancier and creates more options, but the
dedicated property is simpler.
Unfortunately I haven't been able to solve the problem of being able to
use remove-empty with the highest value remove-layer staff. I think this
will have to happen in Hara_kiri_group_spanner::request_suicide but
can't quite figure out the appropriate logic yet.
Any comments on these approaches would be greatly appreciated.
Thanks, Mark
