Yes I do know Lily is brought by volunteers. I've done bits and pieces
for it in the past. I didn't know that documentation suggestions should
go on the bugs list - last time I did (a lot) of work on the
documentation it was all done on the devel list.

I said "the voices get out of sync". I thought that would be enough.
Let's give a simple example ...

<<
  { s1*8 s2. s1*8 }
  { s1*4 \cadenzaOn s1 \cadenzaOff s1*3 s2. s1*8 }
>>

The first {} is seen as 17 bars long. The second {} is seen as 16 bars
long. It wouldn't matter too much if that 3/4 bar weren't in the middle,
but as it is your output will be a mess. Lily will think the second 3/4
is bar 8, not bar 9.

The example in the manual works great as a standalone, but try to use it
in a large piece and it'll bite you (and as a trombonist, this is normal
usage to me). I just thought this version was a lot better.

Except I'd solved the problem, so I was making a suggestion for the
documentation. Which, my past experience suggested, belonged on the
devel rather than the user list.
