Just a thought: it may be easier to fix this by scrapping the completion engravers entirely and having music functions that operate on music streams. For example: a4. a1 a2 a8 in the completion heads engraver becomes a4. a2 ~ a8 ~ a4. a2 a8 This would be a lot nicer as a4. a8 ~ a2 ~ a4. a2 a8 and even nicer as a4. a8 ~ a2 ~ a4. a8 a2 (in addition to completing heads, rearranging based on beat conventions à la autobeam engraver). A music function can glance ahead in time, see what the appropriate way to split would be, and then execute it. The autobeam engraver can be rewritten the same way.
