The missing slurs in GC (→GE1) must be an oversight – the copyist wrote only the part of the slur starting in b. 158, at the beginning of a new line, overlooking the slurring of b. 157. GE2 limited itself to adding slurs in b. 157 (most probably by analogy with b. 153) – the already printed slur in b. 158 was left unchanged.
