Ah, I hadn't noticed that, though funnily enough, it actually makes
the positioning inside the staff much simpler.

I thought I'd seen it before. :) The Steffens example has fewer
lines, but the spacing is the same for the wider staff-spaces.

Any mapping is possible: it's up to the user to write the function
which maps pitches to position, though in this case ly:pitch-semitones
will suffice due to rounding.
\relative c' {
\override Staff.StaffSymbol #'line-positions = #'(-4 -2 0 3 5 8 10 12)
\set Staff.middleCPosition = #-10
\set Staff.staffLineLayoutFunction = #ly:pitch-semitones
% these are wrong due to incorrect legers
c1 cis d dis e
% all OK inside stave
f fis g
gis1 a ais b
c1 des d es
e1 f ges g
as1 a bes ces
}
\layout {
\context {
\Staff
\remove "Accidental_engraver"
\remove "Time_signature_engraver"
}
}
Cheers,
Neil
