Moving them out makes it easier to run them through a compiler, use automatic indentation, and opens the possibility to provide a download link in the future. I verified that all examples compile cleanly. (2-space indentation is used because the examples are already significantly indented in the man page, and we need to keep them narrow so that they display well on standard terminals.)
