There remains another issue with bookparts: Consider a file like

\book {
 \bookpart {
    \paper {
       left-margin = 20 \mm
       right-margin = 40 \mm
    }
    music...
 }
  \bookpart {
     \paper {
        left-margin = 30 \mm
        right-margin = 30 \mm
    }
    more music...
 }
  \bookpart {
     ...
}

There's no top-level paper block, so default-paper will only contain 
what's stored in paper-defaults-init.ly.
The ps output engine in framework-ps.scm:92, however, looks for a 
>global< line-width. Currently, this line-width is just the default 
line-width calculated in paper.scm (set-paper-dimensions) or, you can 
also do:

\paper {
 line-width = 14232 \mm % Today I want to wallpaper my room with sheet 
music
}
\book {
  \bookpart {
     \paper {
         ...

This value will be written in the output ps file, but seems to have no 
effect.
To sum up: What's the intention of this line-width value in ps output files?

Cheers,
