New issue 1227 by RalphBugList: \autoBeamOff has no effect on other voices  
when used in a global variable/ghost voice.

1) \autoBeamOff has no effect on other voices when used in a global  
variable/ghost voice. It has to be turned on explicitly for each voice.  
This is probably intentional but AFAIK not mentioned in the docs.

2) \autoBeamoff shows strange effects in combination with 16th notes and  
\partcombine. \autoBeamOff only effects 16th notes when they happen to be  
in the first measure of a combined part. All following measures containing  
16th notes are beamed automatically as if automatic beaming had been turned  
on again. This looks like a bug to me!? (No problems with \autoBeamOff in  
standard polyphonic notation)
In combination with \autoBeamOff \partcombine seems to require some curly  
braces, e.g.:

   \partcombine { \autoBeamOff\MusicPartOne }  { \autoBeamOff\MusicPartTwo }

I didn't find this information in the docs.

This is probably an argument for eliminating \autoBeamOff.  As can be seen
in ly/property-init.ly, \autoBeamOff is an alias for

\set autoBeaming = ##f

If you want it to apply in a global voice, simply do

\set Score.autoBeaming = ##f

The same problem was reported in 2003, so it'd probably be worth getting  
this information into the documentation?
