This is a limitation of the engraver, unfortunately; leger lines are
printed multiple times for chords and merged notes, which often
results in shortened lines being overprinted.

The attached image shows two further issues:

- semibreves have longer leger lines, so the lack of shortening is
exacerbated by collisions with accidentals;
- if the descending part of a natural reaches a lower leger line, that
line should also be shortened.

I imagine fixing these issues would require a comprehensive rewrite of
ledger-line-spanner.cc.
