New K&R edition

[Romain Kang]

One of my friends, who happens to be in P-H marketing, has had access
to some of the "historical documents" related to the first edition.
The first advertisement comprised just a few lines buried inside of
a much larger display.  Also, one marketing letter (perhaps from one
of the authors) noted that there were approximately 130 UNIX sites,
and that P-H should expect to sell an average of 9 copies per site!

(At last count, over a million copies of the first edition had been
printed...)
