Both accents in A1 are undoubtedly long accents, which was not reproduced in FE (→EE). In GE1 it is only the mark in the L.H. that can be considered a long accent; however, according to us, a shorter accent in the R.H. is almost certainly an inaccuracy of notation, even if it was somehow justified in the notation of [A2]. GE2 unified the accents and considered the longer mark in the L.H. to be inaccurate.
