The version of FE2 is almost certainly erroneous, since it overlooked the ending of the slur on a new line. According to us, the remaining two versions of the slurring – along with their corresponding variants in b. 49-53 – may be considered equal, since their authenticity does not give rise to any objections; moreover, both are supported by certain musical arguments (cf. b. 87-91).
