The onclick event listener is the same thing Google does with the search results. Perform a search on Google and right-click a link, then you'll see the URL changes to the a Google proxy server that collects data about your click for analytics purposes. The reason is so the whole process is more transparent and the users can see the actual URL they end up with when clicking the link. The intention was not to hide anything, but to keep things as unobtrusive as possible. I'm sorry if it felt any other way!
