It is apparent that the slur in GC is imprecise - it ends on the end of b. 398 (b.56), which was rightly corrected in GE by extending it over to the first crotchet. This diminshes GC (→GE) credibility and raises doubts as for the slur's beginning as well. Therefore, in the main text we adopt the consistent version of EE and FE.
