Re: Vertical space for imaginary, real collisions

[Mats Bengtsson]

Regarding your second issue, I would have suspected the following 
solution to work,
but for some reason it doesn't. Did I miss something or is it a bug?
\layout {
 ...
 \context{
   \Staff
   \override VerticalAxisGroup #'extra-Y-extent = #'(-0.5 . 0.5)
 }
}
