New issue 1724 by brownian.box: DynamicTextSpanner inside Dynamics context  
are shifted due to pedal

DynamicTextSpanner inside a Dynamics context are shifted to the left if  
there is a Pedal inside another Dynamics context.

That leads to really poor output of the DynamicTextSpanner, which are  
shifted left (compared to when they are well aligned without the pedal) and  
so colliding with the bar line.

This is really an issue for every piano score (using the Dynamics context,  
i.e. centered dynamics and pedal on a horizontal line).

      \new Staff = "up" {
        \clef treble
        \repeat unfold 32 c'4
      }
      \new Dynamics = "dynamics" {
        \repeat unfold 2 {
          s1\cresc s1\f s1\dim s1\p
        }
      }
      \new Staff = "down" {
        \clef bass
        \repeat unfold 32 c4
      }
      \new Dynamics= "pedal" {
        \repeat unfold 2 {
          s1\sustainOn s1\sustainOff
        }
      }

Spanners are better (normally) aligned when there is no pedal in otehr  
context.
