FE feature long accents under the last quaver in b. 153, 154 and 156. GE reproduced them as a short 
hairpin, reaching the 1st quaver of the next bar, which does not influence its meaning in this case (Chopin would sometimes use such notation in two-note motifs). The notation of EE is inaccurate (the use of short accents) and arbitrary (the marks having been doubled in the L.H. part, probably suggested by the authentic notation on the 2nd quaver of these bars).
