OMG. That's what I meant.
Of course I thought about this, but I was convinced that making the MMR 
invisible wouldn't work because it would still affect the spacing and 
collision handling.
But this seems to do exactly what I need:

\version "2.19.80"

\score {
  \new Staff
  \relative {
    <<
      {
        \hide MultiMeasureRest
        R1
        ^\markup "Is this centered?"
        _\markup "and this?"
      }
      \new Voice {
        \oneVoice
        c'4 c c c
        \break
        c1
      }
    >>
  }
}


Thanks
