Thanks for the hint! I didn't check the results with altered line positions yet,
but I don't understand what's wrong here – IMHO the scheme stuff mimics
1:1 the code from the original definition.

What is wrong here?
After some research, I found of that line-count is wrong,
I get a value of 5 instead of 4!

So something along

 (let* ((staff-symbol (ly:grob-object grob 'staff-symbol))
         (line-count (if (ly:grob? staff-symbol)
                         (ly:grob-property staff-symbol 'line-count)

is fishy
