Okay, I'll see whether I can find some time to tweak all the variables (I'm 
currently preparing some Urtext editions of Eybler works, then I need to fix 
this texi2html issue with translated file names, etc). Do you have a list of 
all variables that affect the vertical layout now? That would be quite helpful 
for the doc writers, too.

Ah, that name is really more intuitive than the old one!

That is set to a low variable so that scores with ragged-bottom=#f can have a 
small staff distance. It seems that the vertical layout will now always use the 
minimal distance between staves unless stretching is enabled, right?

It's an InstrumentSwitch object, which is the grob created when you \set 
Voice.instrumentCueName = "Solo"
