This is my go at Project Gutenberg ebook/etext coding system detection
adapted to the emacs cvs.

The charset names in the texts are slightly free-form and need an
unhappy amount of massaging.  "list.log" below is what I grepped out
of all the current files (about 23000 of them).

Some charset names are obvious typos (I reported them), but it doesn't
hurt to allow them.
