End of slur in GC, literal reading

End of slur in GC (contextual interpretation→GE) & FE3 (→FE4,FE5) & EE

..

In GC, same as in bar 16 (bar 70 is only marked as its repetition), the end of the slur can be interpreted in two ways. In the main text we give a more likely, conventional interpretation of this detail, present in all editions – only in FE1 (→FE2) the slur in bars 77-78 was entirely overlooked.
