Both the absence of the slur in GC (→GE1) and the one-bar slur of FE have to be considered as an inaccuracy of notation. In turn, the slur of EE is most probably authentic and we adopt it as the base of the main text. However, we shift its beginning in such a way that it included also the grace note, as it can be seen in analogous situations in GC (bars 1 and 45) and FE (bar 45). It cannot be excluded that the copyist confused the staves and wrote the slur of the L.H., running from the beginning of the bar, over the R.H. A two-bar slur was added also in GE2 (→GE3), together with a conventional slur of the grace note.
