Re: Alignment problem with text crescendo in << {...} {...} >> in 2.11

[Mats Bengtsson]

That's a serious bug. A complete example is
\version "2.11.39"
\new Voice { << g2:8 { s8 s \setTextCresc s8\< s } >>  g4 g \! }

Trevor's workaround also has sever problems since the implicit \voiceOne
and possible collisions with hidden notes will affect the layout.
