OK, sounds reasonable. I haven't given the problem much thought,
actually. It was a byproduct while reducing my score to isolate issue
#936.
Perhaps it makes sense to mention in the documentation for
staff-affinity that strange vertical formatting can happen if #CENTER
is used for a context which is not between two other contexts.
