The problem is that the brackets use a spanner, which will properly end,  
while the text style uses separate grobs for each of the texts  
("Ped.", "*Ped." and "*"). Now, if a \sustainOn does not have a closing  
\sustainOff, we can handle that case in the Engraver's finalize () method.  
Unfortunately, it seems that at that time it is too late to create a new  
grob for the final "*", but we don't know before whether we need a  
final "*"....

I've tried to implement the creation of the "*" in ::finalize, but the  
following patch always crashes (valgrind shows access to some unallocated  
memory in the page breaking code):

So, apparently creating a grob for "*" in ::finalize does not work. Any  
idea how to make this work?
