1.3.33.jcn1
===========

* Rewrote Staff_margin_engraver.  Staff margin texts now hang on a new
  breakable item: Left_edge_item.

* Fixed vertical alignment for dynamic elements.  Orphaned dynamic items
  (not supported by a Dynamic_line_spanner) still collide with Staff,
  although they now have staff support, which was supposed to fix this.

1.3.32.jcn4
===========

* Fixed Staff_margin_engraver for "instrument", "instr" is still broken.

* Dynamic elements are only put in a Dynamic_line_spanner if there
  actually is more than one adjacent note-column with a dynamic.
  This breaks the fine looks of all dynamics, again :-)
