Non-stretchable gracenote groups

For some instruments such as bagpipes it is desirable to use groups of several gracenotes that do not stretch with the normal music. This can be achieved by setting the GraceSpacing spacing-increment to zero or to a small value.

\relative c' {

  c4 c c c | \break
  c4 c_"With tweak applied"
  \override Score.GraceSpacing.spacing-increment = #0
  \grace { g'32[ c, g' c, g'] } c,4 c |
  c4 c c c
}

\layout {
