Re: lilypond: merging rests in polyphonic staff

[Blöchl Bernhard]

I do not understand R1*4?

May be you wanted something like that, does not make sense for me and 
may be there are better versions possible, anyway ...

  title = "merging rests"

Key = { \key g\major }

%% ------ Piano ------
rhUpper = \relative c''
