We preserve the notation of GC, in which the accent (long) is not related to 
and it seems to concern the R.H. The notation used in FE was, however, used by Chopin, hence it can be authentic. The short accent in GE is an inaccuracy resulting from the fact that the sign of the long accent did not belong to the set of standard music indications and each time it was interpreted either as a common accent or as diminuendo.
