If you read the Hara_kiri_engraver docs, it says
______________________

Like Axis_group_engraver, but make a hara-kiri spanner, and add  
interesting items (ie. note heads, lyric syllables and normal rests)

Properties (read)

    keepAliveInterfaces (list)
        A list of symbols, signifying grob interfaces that are worth  
keeping a staff with remove-empty set around for.
______________________

If that property were settable (on the fly), we could add  
MultiMeasureRest to (or remove it from) the keepAliveInterfaces as  
desired -- that would solve the problem!

Developers: any chance you can do this (or something similar, with an  
equivalent result)?
I've still got a few Euros burning a hole in my PayPal account...  =)

Thanks,
Kieren.
