4461e45278 Add chapter 4 to root, fix bit rot
Fixing the bitrot in chapter 4 after moving it meant looking at the OCR'd text
on archive.org, which is not good.  Here's how not good it was:

Yeah....  You see why I was so excited by the source text?  :)

This one was easy.  The rest won't be.

93dd3e1ecd Add the .s files (may be broken)
I would not swear these dumped correctly using the procedure described in the
README files.

27bcf5f79c Remove trailing nulls, .pp tags
PIEWriter dot codes are case-insensitive, and I've deciphered that .pp is a
paragraph break.  Replace those with blank lines.  The NUL at EOF was escaped,
but it can be simply deleted.  Did so.

1d9b739d80 Dump all the documents to text files with markup
Looks like CH4 is somewhat hosed, a small amount of bit rot?  Doesn't look like
too much actually.
