do you still need this change ?

It looks like I do,

I had expected that separation-item.cc calls pure_height with start=0 and 
end=INT_MAX for horizontal spacing; then the original test would do just what 
we want without your change.  Now I vaguely remember that breakable columns get 
their skylines differently.

Somebody asks for pure_height of a SpanBarStub with start and end only one 
measure apart, to which the honest answer from a SpanBarStub would be its 
height if that measure were alone on a line, but the answer seems to be used 
for horizontal spacing of longer lines.  That is not good.

have pure-from-neighbor-interface [affect] only extra-spacing-height
That would make more sense, but you need to pick a base Y-extent from which the 
extra-spacing-height extends.
