As was the case with b. 3, in A the long accent is placed right under the note; however, in FE it was moved to the right, hence it could be interpreted as a 
hairpin. This is how it was reproduced – moving it even further to the right – in EE2 (EE1 omitted the mark). The absence of the mark in GE is most probably an oversight of the engraver.
