This enables GitHub to do proper syntax highlighting, thus improving the
readability of multi-line code blocks. As a result, some changes were required
to make the code blocks syntactically correct, since they're actually parsed by
language-aware parsers; primarily, this meant inserting comments.
* Removed extra spacing after bullets in list
* Removed extra blank lines; fixed indentation
* Fixed all links (including examples) to code.google.com to use github.com
instead; deep links to code.google.com redirect to top-level GitHub project
page, thus rendering them useless
* Removed extra strings in Markdown link targets
* Fixed capitalization and grammar
* Added more code formatting
