Now I see why you were marking the entire NoteColumn as cross-staff, if
its Stem is cross-staff.

<< \new Staff="up" { g'8 \change Staff="down" g' r4 r2}
   \new Staff="down" { s2\sustainOn s2\sustainOff } >>

After line- and page-breaking, but before the spreading of staves across
the page, we want to estimate the positioning of the pedal spanner.

Comments above indicated that this code would see the NoteHeads, that
is, a layer deeper in the packaging.
