The default is actually to allow the components of the church rest to
expand to fill the available space within the measure. The symbols
making up the rest are assigned a padding value proportional to the
visual size of the measure.
I think what you're after is some means to limit this expansion. I've
attached a patch which creates a property ("no-stretch") which keeps
internal padding at its minimum value -- 1 staff space. Note also the
test file. I haven't tested it beyond what you see there.
It might be nice to allow a maximum padding. (I find 1.0 for padding
a little close.) That would be easily done.
Sorry that this is a patch you need to apply. Putting this in Scheme
would require extensive recoding.
HTH,
David

Subject: [PATCH] Implement no-stretch for MultiMeasureRest
Ordinarily, church rests expand to fill the measure. This patch
implements the property "no-stretch," a boolean which when #t prevents
the default behavior.
