Something similar that comes to mind here is Alonso Fernandez de Avellaneda and his unauthorized Don Quixote sequel. The story, as I understand it, is that the book took hold too quickly for Cervantes to issue any type of effective dismissal and he had to address the Avellaneda text in his own Part 2 in a type of meta criticism.
Now, I'm not too sure of the accuracy of that story. I heard it on Radiolab I think and haven't read anything else about it. But, in a way, it illustrates what I'm asking.
Edit: Proof-reading is good.
I understand your question, but neither eisegesis nor exegesis are transciption errors. I presume you are thinking of things like homoioteleuton.
