GDP: warning about writing lilypond examples

[Graham Percival]

If you write (or significantly modify) any lilypond examples, be careful 
about the limited spacing in the manual.  Specifically, all examples in 
the manual are created with this block:

\paper {
  #(define dump-extents #t)

  line-width = 160\mm - 2.0 * 0.4\in
  ragged-right = ##t
  indent = 0\mm
  force-assignment = #""
  line-width = #(- line-width (* mm  3.000000))
}


Unless you're demonstrating some funky \paper stuff, you're not allowed 
to change these settings.  So make sure your example looks good inside 
that spacing (ie no leftover bars on the next line, etc).


Inspirational headwords have the same settings, except that the 
staff-size is set to 16.
