GE1
compare
Both versions of the slurring may be authentic, and the version of FE is probably later. However, the fact that GE - the source that was, after all, based on GC - has a continuous slur shows how easy it was for the engraver of FE to misread the manuscript. Bearing that in mind, we take the slurs of EE and GC as our main text. The practical difference in performance is very slight anyway.
