Re: glissando between two notes not joint

[Trevor Daniels]

Hi Eluze

I was thinking of something like this, which works
as long as the fingering is directly above the note:

{
 \once \override Glissando #'(bound-details left Y) = #4
 \once \override Glissando #'(bound-details right Y) = #5.3
 g''2-1 \glissando <<{s} \\ {e''}>> b''-1
}

It might need a bit more fiddling with voices and hidden
notes if you really need chord-based fingering though.
Padding can be adjusted if you want to change the distance
of the end points from the fingering.
