Documented but unimplemented feature for beam subdivisions?

[Mats Bengtsson]

Hi,

According to the 2.13 docs, it should work to do something like
\overrideBeamSettings #'Score #'(4 . 4) #'subdivide #'(((1 . 16) . (2 6 
10 12)))
to specify a pattern for beam subdivisions. However, when I tried it, 
nothing happened and as far as I can see from the implementation, all 
subdivide settings are simply ignored.
Could it be that the documentation describes the planned implementation 
but that the plans changes or were delayed? (The relevant patch is 
http://git.savannah.gnu.org/gitweb/?p=lilypond.git;a=commit;h=edbfb6ad6f5c8d3d0628ac1fc2e18046d9b14ddc)
I would have hoped to use this feature to answer 
http://lists.gnu.org/archive/html/lilypond-user/2010-03/msg00098.html.


Also, for the part that works, namely
\overrideBeamSettings #'Score #'(4 . 4) #'end ...
I find the documentation in NR 1.2.4 Beams "Setting automatic beam 
behavior" misleading, since it says that
"Beam type is either a scheme pair indicating the duration of the beam, 
e.g. (1 . 16) ..."
but as far as I can understand the (1 . 16) does not denote the duration 
of the beam, but rather the duration of the last note of the beam, right?
