The missing slur running from the last L.H. quaver in b. 12 and two subsequent ones in b. 13-14 in EE is a patent mistake of the engraver of that edition.
In FC the beginning of the first of those slurs is missing, which – at least theoretically – results in an ambiguity, as far as the presence or range of that slur is concerned, since the next bar is marked in the manuscripts in an abridged manner as a repetition of b. 12. We assume – like GE, based on FC – that the slur at the beginning of b. 13 is to be taken into account, in its full range, which means that it should also encompass the last quaver in b. 12.
