Title: Tweak some symbols and punctuation to better match the PDF.

Some of these were hard to tell from the orinigal PDF because of the image quality, but I think my changes are closer to the original, if not perfect.

* Fractions (e.g. "1/2") have been replaced with actual fraction characters (e.g. "½") where they are rendered specially in the original. There is one fraction ("a virtual sheet about 1/3 mile square!") that did not seem to be rendered specially in the original, so I left it alone.
* The letter "o" has been replaced by a white circle ("○") in places where the original seemed to be using a white circle, although it might be a white bullet ("◦") or function composition operator ("∘"). It's hard to tell. One of the diagrams in section IV seems to refer to it as an "eyeball". I settled on white circle because it seems to render the most closely to the original.
* I added vertical bars ("|") to the tables in section IV, because they seemed semantically significant in the original.
* Some "=" characters have been replaced with "»" in various places to match the original. It is very difficult to tell exactly what glyph the original is using, but it seemed to be "»" when I compared all the original rendering of the mystery glyph.
* In one code sample (line 1758) two commas were replaced with periods, to match the original.
