Re: Staff switch line (documentation?) bug

[Graham Percival]

Sorry, I don't understand.  Yuval's example looks like a bug to
me -- at least, I can't imagine why you'd ever want that extra line
to appear in a piece, so it doesn't make sense for
PianoStaff.followVoice=##t  to have that effect.

Despite that, is there something I should change in the docs?
