I think we should go through these comments more carefully - some of them may have useful information for someone trying to use these examples (such as this one, which indicates the default port).

If you do the whitespace changes alone, I'm happy to merge that (though don't bother deleting blank lines from the end of files where you don't change anything else - it's inconsequential, and makes more work for the reviewer). Then cleaning up actual code and comments in examples can be done separately.
