Single notes in A (→GE) & EE1

Chopin doubled the bass progression in the bottom octave in the proofreading of FE (cf. bar 19, in which Chopin also reinforced the bass note, adding an octave). The change, which is certainly to be considered to be final, was also introduced – in the form of added quavers under notes – in EE2 (→EE3).
The missing staccato dot (as well as accent) in FE is most probably a result of an imprecisely performed proofreading.
