Glyph for longer MultiMeasureRest

[Thomas Morley]

Hi,

what's the common practice of setting MultiMeasureRest with longer bars?

I.e. which glyph should be used?
LilyPond chooses different ones depending on \time.
I naively expected that the code below would result in the same output
for the different settings of \time.

I didn't manage to find examples in my private library or online and I
still don't have Gould.


\version "2.16.1"

\new Staff {
  \time 7/4
  \compressFullBarRests

  R1*7/4
  R1*7/4*2

  \break

  \time 9/4
  R1*9/4
  R1*9/4*2

  \break

  \time 18/4
  R1*18/4
  R1*18/4*2
}


Thanks,
  Harm
