The range of the 
hairpin in A is not entirely clear – the mark's arms are of different length and it goes beyond the bar line ending bar 76 and the line of the text. The mark in FE could have been added in the last proofreading, together with the correction of the part of the L.H. – it is indicated by the fact that it was completely omitted in GE. The absence of the mark in EEC is probably due to an oversight. In the main text, we assume a possibly literal interpretation of the sign on the basis of A.
