Re: does the custom \dynamic function create DynamicText grobs?

[Kieren MacMillan]

Hi Thomas,

This seems to work:

      \override DynamicText.after-line-breaking =
          #(lambda (grob) (ly:grob-suicide! grob))

But this is the Scheme equivalent of me shooting a machine gun with a blindfold 
on, so please tell me if I've done something wrong.

Thanks,
Kieren.
