New issue 1195 by address@hidden: "Broken crescendo hairpin"  
snippet in "Expressive marks" is broken
http://code.google.com/p/lilypond/issues/detail?id=1195

Reported by David Kastrup:
"The "Broken crescendo hairpin" snippet in "Expressive marks" makes space
for a dynamics mark which is placed above the staff after all.  That is
for the current development version and can be seen on the web page at
<URL:http://www.lilypond.org/doc/v2.13/Documentation/snippets/expressive-marks#broken-crescendo-hairpin>"

This is the snippet:
\version "2.13.28"
\relative c' {
  <<
    {
      \dynamicUp
      \override DynamicLineSpanner #'staff-padding = #4
      r2 r16 c'8.\pp r4
    }
    \\
    {
      \override DynamicLineSpanner #'layer = #0
      des,2\mf\< ~
      \override TextScript #'layer = #2
      des16_\markup {
        \postscript #"
          1.9 -8 translate
          5 4 scale

          1 1 lineto
          1 0 lineto

          fill"
      }
      r8. des4 ~ des16->\sff
    }
  >>
}

Just commenting out the fifth line "\dynamicUp" (which seems like the  
obvious error) isn't the solution: The pp is placed below the hairpin and  
is partly hidden by the white rectangle (see attachment.
So the pp (and maybe the rectangle) have to be moved to better places and  
the pp has to be placed on top of the rectangle.
