Comment #3 on issue 1083 by joeneeman: subdivideBeams fails at the  
beginning of a pattern
http://code.google.com/p/lilypond/issues/detail?id=1083

Actually, this has nothing to do with subdivideBeams, but rather with  
beatLength (and, AFAICT, with the way that beaming properties work in  
general). In 4/4 time, the default is to break beams every beat, but this  
is stored in beam-settings.scm as '(1 1 1 1). When beatLength is 1/8, the  
beam endings get transformed by ending-moments (in auto-beam.scm) to '(1/8  
1/4 3/8 1/2), which means that there are no places to split beams in the  
second half of the bar.
