Seems like a creative thing to do.  This code can (eventually) be made part
of tabNumbersOnly, right?

The current challenge with draw-tab-slur is that it shifts the slur after
the control points are already determined, which means that it may introduce
collisions.  It would be better if the slur *calculation* code could be used
to fix this up, instead of the slur *printing* code.

I think working up a patch based on this is probably OK, but it should at
least have a TODO in it.
