In A, the short 
mark is placed in b. 6; however, since it reaches only the 1st crotchet in that bar, it is obvious that it concerns the f1-g
1 step between the bars, which we give in the main text. The versions of editions are based on the interpretation of that mark performed by GE1, in which its right-hand ending is led to the 2nd beat of the bar, which has no basis in the notation of A. In spite of minor differences in the range of the marks in the editions, we regard them as different, since each may suggest a slightly different beginning or ending of the crescendo, while the mark in FESB actually resembles a reversed accent.
