New issue 2243 by address@hidden: Incorrect subdivision of beams

Reported by Xavier:

Just reported on the French Users mailing list:

%%%% Snippet

%% subdivideBeams does not work anymore with 16th tuplets.
%% With 2.15.26 only the second beat is subdivided as expected.
%% Worked well with stable 2.14.2, so this is a Regression.

\version "2.15.26"

\relative c'' {
  \set subdivideBeams = ##t
  \set baseMoment = #(ly:make-moment 1 8)
  \set beatStructure = #'(2 2 2 2)
  \repeat unfold 8 {
    \times 2/3 { c16 e d }
  }
}

PH reports that 2.15.18 is OK, the beam pattern changed by 2.15.21 and  
again at 2.15.24.
