+The use of grace notes within voice contexts confuses the way the
+voice is typeset. This can be overcome by inserting a rest or note
+between the voice command and the grace note.

 Grace sections should only be used within sequential music
 expressions.  Nesting or juxtaposing grace sections is not
 supported, and might produce crashes or other errors.
