New issue 1216 by PhilEHolmes: DynamicTextSpanners should end like hairpins
http://code.google.com/p/lilypond/issues/detail?id=1216

From Jon Arnold:

DynamicTextSpanners in their current state will prevent hairpins from being produced properly if the space is small.

The DynamicTextSpanner should have the same right boundary as a hairpin (i.e. a \cresc should end at the same place as a \< ). They should also behave the same way at barlines.

The following example demonstrates the behavior of a \cresc and a crescendo hairpin at the same place. Notice that the following diminuendo hairpin is cut off in the first example. The final example shows the proper diminuendo hairpin, as the \cresc is ended a beat earlier than in the original music.

The second set of examples shows similar behavior but ending at a barline.
