In GC bars 89-90 end the line of text. This caused the copyist to have erroneously omitted the opening part of the slur – he wrote only the ending fragment in bars 91-92. In GE this fragmentary slur was overlooked or omitted. For the joining of the slur in FE to the preceding one see the note in bar 88.
In A, the way the slur ends makes it clearly a "tenuto-slur". This was properly rendered only in EE. See also the note in bar 92.
