Re: moving colliding rests

[Jonatan Liljedahl]

You mean that I could do a \restsUp for all colliding rests manually? I
was hoping there was a way to automagically handle such collissions,
just as it's already done (?) with two voices on the same staff with
\voiceOne and \voiceTwo, but disabling stem direction.
