It may be possible to include the tie/slur/glissando in the
tab_note_heads_engraver, but I haven't yet been able to get it to work
properly.

However, we can't do the whole display-cautionary thing in the engraver,
because the engraver doesn't know about such things as split ties.  That has
to be dealt with in the tab note head callback.

The problem with the harmonic brackets is orthogonal to this problem.  I
started work on it, but I have to sort out the various parenthesize
functions before I know how to fully deal with it.  It's on my list, but I
want to get this one resolved first.

Thanks,
