Hmm…tricky…interesting…
LilyPond’s accidental placement algorithms make a deep assumption that
accidentals should always be to the left of elements in the skyline of the note
columns happening on a staff at a given moment. Turning this off would require
massive Scheme hackery. This hard-codedness probably because the layout makes
is seem that you have a measure of 5/8 - the accidental (and note) no longer
seem to belong to the 4th 8th note.
Could you send an example of what you want to accomplish in the layout -
perhaps a bit more robust if need be.
Cheers,
