I've decided to keep the reverts for the On predefs, since \once does

Yuck. The problem seems to be that the override takes effect at the first beat
in a bar, after the paper-column for the previous barline has been generated,
and the \once makes the override expire before the next bar.
Unfortunately this also means that
\override Score.NonMusicalPaperColumn.line-break-permission = #'allow
R1
only has effect /after/ the R1.
We have a workaround for that timing problem in \overrideProperty, and then
\once works fine with
autoLineBreaksOn = {
\overrideProperty Score.NonMusicalPaperColumn.line-break-permission #'allow
\override Score.NonMusicalPaperColumn.line-break-permission = #'allow }
autoLineBreaksOff = {
%?? \overrideProperty Score.NonMusicalPaperColumn.line-break-permission ##f
\override Score.NonMusicalPaperColumn.line-break-permission = ##f }
I put the %?? because I'm not sure whether it is more intuitive if
\autoBreaksOff
R1
should forbid a break before the R1, or mean "here is your last chance to break,
Lily".
