According to us, the 
hairpins written in A were initially overlooked in [FE0], and while completing the performance indications in this place (see the adjacent note), Chopin added in a proofreading of FE (→GE1) a long accent over the first of last three semiquavers. We give this version in the main text. In the subsequent GE the accent was replaced with ; the coincidence with the notation of A is most probably accidental. In EE2 the sign was overlooked, which was corrected in EE3 (→EE4).
