In the main text, we omit the cautionary 
before c3, present in all sources except GE3. In the same group of sources, there is no 
before d
2, which we do not consider a mistake, since the first part of the roulade is written there with the use of an octave sign, so that the before the 2nd semiquaver may be considered valid also here.
