I've added a zip archive of corrected pages, where I corrected some of the errors that were pointed out to me by Christian Robert. You can access it here:
Some of the changes Christian suggests require rewriting parts of the text; I've started doing that, but publishing the whole book again will have to wait until the next corrected edition can come out (say the publishers---apparently they have to wait till the existing copies are sold). Until the corrected edition appears, I will keep updating this blog and the book's home page with corrections.
Please tell me if you find more problems in the text.
