The 
hairpin in FC was extended by Chopin so that it ends more or less where the mark in FE (→EE) does. Both marks encompass bar 44, in which the R.H. part motifs – the two-note ending of a descending motif (in a 'strong-weak' scheme) and a rest – practically excludes the performance of a crescendo. Therefore, it refers to the L.H., particularly to its top voice. This sheds new light on the extension of the hairpin in FC – it was probably an attempt at fixing the copyist's mistake without resorting to deletions. Due to the above, in the main text we give the FE hairpin, most probably corresponding to the [A] notation.
In GE, the mark was shortened in order to avoid the rest (since the mark was referred to the R.H.).
