Let the documentation patches close issue 1566.

Valentin in his original report 
<http://lists.gnu.org/archive/html/bug-lilypond/2011-03/msg00331.html> thought 
the beam was hidden by \hideNotes, knew how to get what he wanted, and suggested it 
might be simply documentation.  He tentatively asked for the c8. d16 to be 
auto-beamed (but in fact it already is).  Nobody asked for beams to change properties 
mid-stroke.  So nothing to do 'codewise' in response to 1566.

We missed the underlying issue, though.
{ r8
  \once\override NoteHead #'color = #blue
  \once\override Beam #'color = #blue
  c''
  override Beam #'color = #red
  c''8. d''16 % These two get auto-beamed in blue
}
It seems the auto-beamer is thinking about drawing a blue beam starting at the 
first eight note, changes his mind when he sees the dotted rhythm, but still 
holds on to the request for blue.  If that's a bug, it should be tracked free 
of the confusion of 1566.
