It seems to be impossible to decide whether Chopin meant here a staccato dot (like in the next bars) or a wedge (like in the previous ones). The editors would often confuse these marks; it is also difficult to differentiate between them in the Chopinesque autographs. In the main text we give a dot, since FE is the only edition based directly on [A].
