I wanted to mention that for some reason none of this stuff works
unless it appears before the score block. Both dump-spacetime-info.ly

are located at the bottom of the file, after the score block, there are
no prints. In case anyone happens to read this and is bitten by the
same thing.
I looked into the code and there is an after-line-breaking in system.cc
(void) g->get_property ("after-line-breaking");
This is used in a similar way to other places I see after-line-breaking
used, such as haripin.cc. So I presume this get_property() call has a
side effect of running scheme code (ie. a callback).
That means:
\layout {
\context {
\Staff
\override System.after-line-breaking = #printPage
}
}
should work. And it doesn't. I tried \Score context, no context, and
even \Voice context. None of them printed anything. If I'm missing
something about how this works, I can't see it.
