Notation manual - 1.3.3 Expressive marks as lines - glissandi

[Anthonys Lists]

Arghh! Tweaks and workarounds!

"For a contemporary glissando from a note, you can use hideNote and 
cadenzaOn/Off". Except I've tried it and the side effects have buggered 
everything else up !!!

As soon as you start combining voices - like I separate markups, time 
signatures, etc from notes - as soon as you put a cadenza in one voice 
and not the others, they get out of sync and mess up royally.

So I tried to use a chord with a hidden note, except that it appears you 
can't put a rest into a chord ...

What I've done, which works for me, is to use a tuplet instead. imho 
this is much better, not least because it doesn't have nasty side effects.

I attach my little example below, if someone would care to put it in the 
manual instead of the one that's there.

{
  \once \override TupletBracket.bracket-visibility = ##f
  \once \hide TupletNumber
  \times 2/3 { r4 \hideNotes c'8\glissando \unHideNotes } c''2->
}

Okay, my example is to a note, not from, but when you're trying to do a 
score, or multiple instruments where some have "contemporary glissandi" 
and others don't, the example in the manual is going to cause grief. 
This version doesn't have side-effects.
