Re: \unfoldRepeats doesn't

[Mats Bengtsson]

In my opinion, it's rather a bug (or at least strange) that you do get 
the repeats
when you don't have the \unfoldRepeats command.
The basic philosophy behind LilyPond is that the input should represent
the music itself, not primarily how it's represented. Your \music variable
only describes 4 measures of music, not the 5 measures you get when you
play the repeats. I always include the \repeat commands together with the
music, i.e.

music=\relative c' {
 \repeat unfold 8 c8 |
 \repeat volta 2 {
   \repeat unfold 8 d |
 } \alternative{{\repeat unfold 8 g,|}{ g a b c ~ c2 }}
}

If you look carefully at the output of your example, you will notice that
the \unfoldRepeats actually makes a difference, since you get an empty
5th measure which is the result of unfolding your \global.
