Title: fix 37646: bad continued tie with seconds

Instead of starting a continued tie from some arbitrary distance to the left of the chord origin (which might not be enough to clear backnotes or other markings), instead start from just past the clef/keysig/timesig. This is what Gould recommends anyhow.
