The slur, added in later GE in bar 4 certainly after an authentic slur in analogous bar 20, can be considered to be a justified addition to the version of A and the remaining editions. In the main text, however, we preserve the differentiation between bars 4 and 20 in this detail, as it may suggest a subtle performance nuance. (In As and AI, in which the 2nd and 3rd crotchets are identical, the slurs are absent both in bars 4 and 20.)
