In the editors' opinion, the slur in A is a remnant of the original version, as in bar 180. In the discussed bar the longer slur added by Chopin in GC may even be regarded as joining the short one, which confirms our conviction that the long slur was meant by Chopin to replace the short one. It was reproduced that way in GE. The slur from A was overlooked in both FE and EE.
