clusters interrupted by rests but not multi-measure rests

[Mark Knoop]

\makeClusters \music produces expected output when \music contains a
rest, but multi-measure rests and skips do not interrupt the cluster.

Whilst the documentation for Clusters includes under Known issues and
warnings: "Separate clusters need a separating rest between them",
there doesn't seem to be an issue for this in the tracker. Surely this
is not the intended behaviour?

\version "2.19.59"
\makeClusters {
  \textLengthOn
  <c' g'>2 <c' c''>
  r1^\markup "clusters stop for Rests"
  <c' g'>2 <c' c''>
  <>^\markup "but not MultiMeasureRests" R1
  <c' g'>2 <c' c''>
  s1^\markup "or Skips"
  <c' g'>2 <c' c''>
}
