release: 1.3.89

======

* Some fixes to Coriolan.

* Fixed some stupid core dumps processing Coriolan.

* Fixed several problems with part-combiner's part-switching.

* Fixes for ASCII output.

* Added feature to part combiner that should allow part-switching only
  for entire measures.  Currently, it is controlled by a new
  property changeMoments (A . B):
    - only switch when !(A mod now),
    - decide whether to switch based on music during time period B.

* Made bugfix: Sequential_iterator::get_music (M): mustn't return music
  later than M.

* Added skip (M) to some iterators.

* maintain minimum-length by shifting for hyphens at start of
line. (patch courtesy Christophe Rhodes)

* mudela-book fixes (courtesy Tom Cato Amundsen): documentation
update, LaTeX example, landscape support.
