Re: [Lilypond-auto] Issue 3385 in lilypond: Ottava with cross-staff messes up beams

Comment #11 on issue 3385 by address@hidden: Ottava with cross-staff   
messes up beams
http://code.google.com/p/lilypond/issues/detail?id=3385

Previous versions let the beam cross the ottava bracket, but with some  
reason.

Whether to knee the beam depends (in the general case) on staff spacing,  
and staff-spacing could be affected by the placement of the ottava bracket.

Version 2.16 places the ottava bracket relative to the staff first,  
ignoring the cross-staff beam but fitting over anything else, then does  
staff-spacing, then sets the beam.

By contrast, with Scripts like in issue 3363, earlier version would mark  
the Script as cross-staff so that it would be ignored for staff-spacing,  
and then place the script after the beam is set.

The unpure-pure-containers patch keeps track of whether an  
object 'aligns-to-cross-staff' so maybe that is supposed to set scripts.

I'll revert the patch that caused the visible change.

  \new Staff = "lower" { s2
  \ottava #1 c'''8
  \change Staff = "upper"

  \change Staff = "lower"
  r4 \ottava#0 }
