Omission of the 
mark at the end of the pieces is characteristic for Chopin's pedalling and is featured in numerous works, e.g., in the Etudes in C major, No. 1, C
minor, No. 4, C major, No. 7, F major, No. 8, E
major, No. 11. The revisers of GE and EE considered it as an inaccuracy of notation of FE.
