a quick non-technical writeup on the Clipper chip -- corrections

[Jeff Kellem]

Here are some minor corrections to the the non-technical writeup I posted
earlier this evening.  Note, that I also already corrected the typo
regarding how the keys were constructed.

Ignore the line numbers.. they'll be incorrect, as this is part of a larger
article.

FYI...
