The easiest thing to do would be to find the control points and change the X 
positions such that they maintain the same relative distance but finish just 
before the bar line (instead of the next note column).

To get the slur to know where this bar is, just create a custom engraver with a 
slur and a bar line acknowledger and have the slur stash the barline as an 
object 'foo whenever context property myContextProperty is set, and then set 
myContextProperty to true before volta repeats.
