Editing should be, especially in the case of old writers, a counselling rather than a collaborating task. The tendency of the writer-editor to collaborate is natural, but he should say to himself, 'How can I help this writer to say it better in his own style?' and avoid 'How can I show him how I would write it, if it were my piece?'
