1.3.79.jcn2
===========

* Fixed some silly url reversals in FAQ.

* Finished Coriolan music entry (again); entered second viola part.

* Updated Coriolan to use part combiner on Voice level for wind parts
  and on Staff level for violi and bassi.

* Part-combiner now uses duration inquiry, which fixes rhythm-related
  bugs in determining solo/a2.  Also, rests are taken into account.

* Another crude fix for almost unexplainable (with a gdb that dumps
  core on ly_display_scm) all-zero control points slurs.

* Fixed slurs that crossed through stems and note heads.  Note
  that beautifying of ugly slurs is still broken.
