I think this dispute deserves an issue in our tracker. Obviously, there are two engraving schools, an older one to which Paolo refers (and what I would consider standard, too), and a newer one referenced by Joram. And please add scanned images of piano music to the tracker! I can imagine that this eventually leads to two piano pedal styles in LilyPond. Werner
