Beams over rests

[Paul Hodges]

The composer I'm working on is very fond of having beams over rests - 
and indeed it helps a lot in reading his more complex rhythms.  However, 
LilyPond is treating rests differently from notes, in that beam 
positions are adjusted to suit the notes, whereas rests are then 
adjusted to suit the beams.  So I get this kind of layout:
However, the publisher wants rests to remain in their standard position, 
like this:

with occasional compromises to this extent:


I can obviously force this in individual cases, but again, is there a 
global adjustment I can make to get nearer to what I'm being asked for?

Thanks,
Paul
