The stem prolonging the g quaver was overlooked both in FE (→EE1) and GE). Chopin added it in FED and FES; moreover, in both copies he also prolonged the last a quaver. We consider that addition, most probably introduced independently in each of the copies, a development of the original idea and adopt it to the main text.
It remains a mystery how the reviser of EE2 found out about those prolonged notes.
