Fix 2005/mikeash for linux

The problem was to do with an unknown escape sequence (\N) which was
used in a string (also in a comment and the 'N' was referred to in
code). It had been '\Newline' but this was changed to '\nNewline', the
array size that stores part of the string was increased by 1 and the
code was updated to check for 'n' instead of 'N'.

I also fixed a problem in README.md: might not have not might not of.

+Cody fixed this to work in linux. The problem was an unknown escape sequence,
+`\N` which caused a funny compiler error:

+The problem was that in the string above there was a `\Newline` but this is
+invalid C. This was changed to be `\nNewline` and then, because the code is
+supposed to output itself when fed itself, the reference to `'N'` had to be
+updated in both the string and the code to be `'n'`.

+The array size of `c` was updated by 1 out of caution just in case as the array
+is used to store at least part of the string.
