No slur in A (→GE→FE)

A slur added in EE
..

In EE, a slur was arbitrarily added in the first half of the bar for the upper voice. The addition makes musical sense, yet there are no grounds to consider it authentic.

A (→GE→FE→EE1)

Small slurs added in EE3
..

In EE3, small slurs were added joining grace notes with their main notes. This is definitely an arbitrary revision made for the needs of that edition.

When writing A, Chopin overlooked the fact that in the passage ending the run a  is necessary not only before the last note but also four notes earlier in order to lower c3 to c flat3 (or only before that earlier note, depending on the adopted principle for accidentals before notes with an octave sign). The error was corrected in GE (→FE) by moving the  before the fifth note counting from the end of the bar. In EE this corrected notation was supplemented by again adding the sign before the last note.
