Among the four source versions of the slurring, only the first two – GC and EE and FE – are probably authentic. The version of GE1 is certainly erroneous – the engraver confused the bars and inserted the division of the slur one bar too late. In turn, the reviser of GE2 (→GE3) probably assumed that the slur of the grace note and the phrasing slur, which merge in GC, create one slur beginning from the grace note.
