The vague mark in A may be interpreted as a slur. It seems that Chopin went out of ink at the time of writing, however, he did not take care of a discernible notation in A, nor did he add the slur while proofreading FE. Therefore, we do not include this mark in the main text. In EE3 (→EE4) a whole-bar long slur was added under the semiquavers.
