Comment #1 on issue 2048 by address@hidden: shiftDurations with  
negative 2nd argument loops indefinitely
http://code.google.com/p/lilypond/issues/detail?id=2048

The troublesome second parameter, how many dots to add, should be  
deprecated because adding dots does not uniformly scale durations.
 \displayLilyMusic \shiftDurations #1 #1 << { c'2. d'4 } r1 >>  % 3/4 + 1/4  
= r1
gives
 << { c'4.. d'8. } r2. >>  % 7/16 + 3/16 not= 3/4
