Comment #7 on issue 1654 by address@hidden: Collision between lyrics  
and items on the next system

There is a side effect of this fix.  In order to get fixed system-system  
spacing previously, it was only necessary to set 'stretchability to 0.   
Then the systems would be spaced fixed distances apart from the center  
staff lines.

Because we respect padding now, it is necessary to set padding to a  
negative number in order to be assured that the systems will be at a fixed  
distance, even if it causes collisions.

In response to Phil (comment 3), there are some people (e.g. Trevor Baca)  
who want to have *fixed* system-system spacing on every page of the score.   
The new spacing engine facilitates doing that.

I agree with the fix that Keith pushed, because now we have a way to get  
*both* behaviors.  The user can now control it.  I just wanted to get the  
new behavior documented, at least in the patch string.

\paper {
  system-system-spacing = #'((basic-distance . 16)
                             (stretchability . 0)
                             (padding . -100)
                             (minimum-distance . 0))
}
