Okay, noted.  This should be easy to fix, since the interval would
just need to be expanded slightly, maybe depending on slur thickness.

Yeah, that's a big problem.  I need to do a more thorough
investigation of the slur code to figure out why that's happening.

Also, looking through git history, the function I removed in my patch
(Slur_score_state::breakable_bound_item) was added in 2006 by Han-Wen
to fix #120.  With my patch, #120 reappears.

Back to the drawing board for me.  :-)
