MMRests cause weirdness following \cadenzaOff

[bobr...@centrum.is]

I've been wrestling with this mystery for some hours.  I've finally found how 
to trigger it. The multimeasure rest causes the duplication of the rests in the 
display in previous measures.  A non-multimeasure rest does not result in the 
weird duplication.  If this is a known issue I missed the notice.
