Ah, yes.  I hadn't thought through the logic carefully; I was just
implementing Marc's logic in C++.

Glissandos and slurs are irrelevant for determining tied-to.  A note is
tied-to if it's at the right hand end of a tie.  Whether it's
parenthesized or not is determined by the presence of a split tie, a
glissando, or a slur.

So we don't need to acknowledge glissando or slur.  Just tie and
note_head.

Got it!

Thanks,

Carl
