My apologies: I hadn't seen cc-guess-view-guessed-style.  I don't think
the function as it is does quite the right thing, though.

That would be much better.

Not quite: the guessed style only includes two style variables.  I think
it should be printed out as inheriting from the default style.  Something
like:

    (c-add-style "*cc-guess*<filename>"
     '("gnu"
       <guessed style>
      ))

What do you think?  Would it perhaps be better to make the *Guessed
Style* buffer R/W, allowing the user to edit the new style before copying
it to his .emacs?  I'm not sure on this one.
