The code takles the Bug described in
   
http://lilypond.org/stable/Documentation/user/out-www/lilypond/Setting-automatic-beam-behavior.html#Setting%20automatic%20beam%20behavior
 "It is not possible to specify beaming parameters that act differently 
in different parts of a measure. This    
   means that it is not possible to use automatic beaming in irregular 
meters such as 5/8."

With the present auto-beaming, I can only specify the length of the 
first beam, all others have the same length (implemented via a modulo 
operation).
Especially for odd length measures, I would like to be able to beam 
differently automatically,
   e.g in 5/8, [a8 b]  [c  d  e].
With the patch, the user can specify each position a beam should end, so 
for the above example, these are 2/8 and 5/8,
   \property Voice.autoBeamSettings \override #'(end * * 5 8) = 
#(make-moment 12 8)
(where 12 = 2*5 +2 specifies twice the position 2 to get a number >=5 )
but not 2/8 and 4/8 achieved  by using
   \property Voice.autoBeamSettings \override #'(end * * 5 8) = 
#(make-moment 2 8)

I hope I have made the point clearer.
