It's probably a step back, but at least we're internally consistent now. Actually, I have some objections to issue 347, but I'll put those in the appropriate place. > > Unfortunately, I linked to the wrong part of that thread; it's around > here, http://lists.gnu.org/archive/html/lilypond-user/2008-08/msg00444.html, > where it's pointed out that the ancient headword occupies more systems > after your fix for #600: the spacing is too loose for the ligatures. Ah, sorry, I was looking at completely the wrong issue. Without doing any investigation, I think the problem is caused by the way the ligature engravers work: they allow the normal Note_head_engraver to do it's job, then they destroy all of the noteheads and cram new ones into a single Paper_column. This means that there are a bunch of empty Paper_columns floating around that were created to hold notes that are now scrunched up into a ligature. The extra Paper_columns confuse the spacing engine; I've encountered them before. The real solution is to set the note head engraver to ignore notes in a ligature and to rewrite the ligature engravers so that they look at note events instead of piggy-backing off the note head engraver. But I'll see if there's a special-case spacing hack that will do for now.
