And that's mainly what I was trying to find out. For me, the expected
behavior is that with a lone duration, the rest would be repeated if
it is the object immediately preceding the lone duration. If it turns
out that most people would expect that rest to be ignored and for
LilyPond to keep searching backward till it finds a pitch, then that's
fine. Not what I expected but if I'm in the minority then code
operates as it should. If I were in the majority then it would seem to
be in everyone's best interest if the behavior were changed.
