Fold out repeats with alternatives

[Johan Vromans]

Hi,

Sometimes I feel the need to make life easier in situations like this:

  <big series of notes> <some notes1> <another series of notes>
  <big series of notes> <some notes2> <another series of notes>

Something similar to:

  \repeat unfold 2 {
    big series of notes
    \alternative { { some notes 1 } { some notes 2 } }
    another series of notes
  }

It's not a big deal -- it's just that it would be handy.
