This patch cleans up the engraver part of page-turning. I got rid of all
the clutter in paper-column-engraver in favour of doing things in

The main change algorithmically is that I defer everything until the
finalize() step. That is, during interpretation I just build up lists of
potential breaks, manual breaks and volta repeats. It probably makes
things a tiny bit faster since the algorithm for revoking turns during
repeats is now linear. More importantly, it solves a problem where the
old engraver would override manual turns.

Here's the ChangeLog, and I promise I will remember the patch...

2006-09-09  Joe Neeman  <address@hidden>

        * scm/define-context-properties.scm
        (all-internal-translation-properties): remove properties that
        were used to communicate page-turn stuff to the paper-column

        * lily/ (robust_scm2string): new function

        * lily/ Clean up page turn stuff

        * lily/ Re-write the page turn logic here
        instead of cluttering up
