 /*
-  Compute the column of the right-items.  This is a big function,
-  since RIGHT-ITEMS may span more columns (eg. if a clef is inserted,
-  this will add a new column to RIGHT-ITEMS. Here we look at the
-  columns, and return the left-most. If there are multiple columns, we
-  prune RIGHT-ITEMS.
-
-  If we end up pruning, we add a left-neighbor to every column that
-  gets pruned. This ensures that loose columns in cross-staff music
-  do indeed get marked as loose. The problem situation is when a voice
-  passes from staff 1 to staff 2 and a clef appears later on in staff 1.
-  Then the NoteSpacing attached to the last note in staff 1 has two
-  right-items: one pointing to the next note in staff 2 and one pointing
-  to the clef. We will prune the clef right-item here and, unless we add
-  a left-neighbor to the clef, it won't get marked as loose.
+  Compute the left-most column of the right-items.
