I wouldn't recommend doing that as a way to start, because bend indications
always go between two sequential notes, and slurs can span as many notes as
desired.

For hacking on it, when you don't have a bend_engraver to create a different
kind of spanner, I can see that torturing the slur_engraver can be helpful.
But if you look at David's sheet, you'll see that sometimes bends are
enclosed inside of slurs, so losing the slur to the bend is probably not a
good approach.
