ps changes betweeen 2.7.29 and 2.8.2 broke tabloid booklet

[Graham Percival]

I produce tabloid booklets of my music (fold tabloid sheet in half to 
get letter-sized pages).  The method I use to produce them currently 
does not work; it worked in 2.7.29.  I'm not certain if any ps changes 
went into 2.9 but not 2.8.2.

1) use lilypond-book to produce normal ps and pdf.  (well, 
normal-looking; I know little about under-the-hood ps stuff)
2) run this:
psbook $1.ps | psnup -2 -ptabloid -Pletter | ps2pdf -sPAPERSIZE=11x17 - 
tab-$1.pdf

With 2.8.2, the final ps2pdf fails.  Interestingly, I can run ps2pdf on 
the original .ps (produced by lilypond-book), but when I try to run it 
on the result of the psbook and psnup, it produces this:
