Staff spacing and collisions

[Oscar van Eijk]

Hi All,

I'm 'Lilyponding' a small prelude I wrote. It's only one page, but I
can't get it without collisions.

I attached a PNG, if that's not clear enough; the PDF is at
http://vaneyck.terra-terra.com/Senorio.de.los.Llanos.pdf.

My problem is mainly the slur above bars 19 and 20 that collide with the
Pedal sign of bar 14.
It could easily be solved if the staff space of the second line would be
decreased a bit, but I can't find how to achieve that.
I've been playing around with "\override VerticalAlignment
#'forced-distance = #x", but that doesn't seem to work (it signals
"cannot find property type-check for `forced-distance' (backend-type?)")

Also the 'keep-fixed-while-stretching' didn't bring me any result.

Any suggestions?

Oh yea, I'm running 2.11.40 :)

Thnx,
Oscar
