Seems like

    #'line-break-system-details
    #'((fixed-alignment-extra-space . 15))

works great, but that

    \override Score.NonMusicalPaperColumn #'line-break-system-details
= #'((fixed-alignment-extra-space . 15))

is silent.


Question: what's the intent of \overrideProperty? (Ie, when's the
right time to use \overrideProperty instead of \override?)
\override changes the initialization of a Grob. Since Score.NonMusicalPaperColumn grobs are created and initialized before a normal \override is processed, it has no effect on Score.NonMusicalPaperColumn doesn't work.
