This sounds like an answer to a question I didn't ask.  I don't doubt that the 
arc in Werner's example is semantically a tie.  What I am wondering is what 
kind of LilyPond grob should represent the arc, and I'm thinking that it should 
be a Slur because of its shape, not a Tie because of its purpose.
