Re: paper spacing variables not being respected for a score inside markup

[Jason Pratt]

Aaron, thank you!

I promise this will be my last follow up to this on the bug list.

This example is exactly what I needed! It both shows the solution to
my problem and gives me a better understanding of where the problem is
coming from. I think I had tried to use nonstaff-nonstaff-spacing to
fix my problem previously, but either didn't put it in the right
place, or didn't alter staff-affinity at the same time, which seems to
be required to make the spacing work as desired.

Also, the idea of mixing TeX and LilyPond to better control layout is
intriguing, although I suspect it might make it even harder to track
down layout issues.

Thanks again!
