 Back on topic

WHy does measure now have no spacing out duration even though I use { }
around the whole feather area? See it works then it doesn't work. Why am i
wrong? I tried 1 2, 2 1, 1/2, and 2/1.

\new Staff
\relative c' {
  \override Beam.grow-direction = #LEFT
  \featherDurations #(ly:make-moment 2 1)
  { c32[ d e f g f g f]}  c4 c c |
  \revert Beam.grow-direction
  c4 e d f c d e f d f


}
