Gabriel-Marie,
attached you'll find the most recent coding.
It indeed needs a newer devel-version because of `ly:item-get-column'-usage
David,
thanks a lot for your research and findings.
Your suggestions are all implemented leading to geat simplifications.
In `keep-at-line-begin' I added some fool-proof.
Regrettable StanzaNumber does not respond correctly for 'break-visibility...
Thanks,
Harm
\version "2.19.44"
