I expect the answer is that it hasn't been. And we can't simply incorporate
the copyrighted code from the book into Emacs without having copyright permission
from the authors. However, if you could code the ideas up from scratch, without
copying the book's code, that would be a nice addition to Emacs. Another possibility
is that you could contact Ed Reingold and ask him whether he'd be willing to
donate the code; perhaps if enough people ask, he'll change his mind.
