Doc bug: beams

[Nicolas Sceaux]

Hi,

It seems that the last example in NR 1.2.4 Beams: Setting automatic  
beam behavior,
is broken. (I'm looking at lilypond.org 2.13.4 doc). This example  
shows three bars
of 16th note, grouped by 4, despite the beam settings override on the  
2nd bar.

Maybe the example should be changed to eg.:

  \time 4/4
  \repeat unfold 8 a8
  %% group 8th notes by 2
  \overrideBeamSettings #'Score #'(4 . 4) #'end #'(((1 . 8) . (2 2 2  
2)))
  \repeat unfold 8 a8
  %% revert the new rule
  \revertBeamSettings #'Score #'(4 . 4) #'end
  \repeat unfold 8 a8

Perhaps it would be nice to show in this section how to override the  
default
beaming settings globally, in a \layout block; stating that instead of  
repeating
in each score a beam setting override like:

   \overrideBeamSettings #'Score #'(4 . 4) #'end #'(((1 . 8) . (2 2 2  
2)))

it is possible to set this behavior for all scores using (at top level):

   \layout {
     \context {
       \Score
       beamSettings = #(cons '(((4 . 4) end) . (((1 . 8) . (2 2 2  
2)))) default-beam-settings)
     }
   }

or is it considered too advanced for this section?
