I am forking this as a separate thread from "Preventing tempo marks stacking

This decision makes sense in most cases, but not when the first note in the 
measure is a MultiMeasureRest. In the example below, the MetronomeMark looks 
weird to me; I think it should be aligned with the BarLine. 
 
\version "2.17.29"
{
  \compressFullBarRests
  R1*20
  \tempo "Tempo"
  R1*20
}
