Takes offsite links that stick the original URL into an onsite link with extra parameters and changes the href to that original URL.
As of
Supports pages crawled by Wayback Machine. This is meant for offsite links that are on-site links with the offsite URL and some extra parameters, yet don't have any kind of "offsite link" warning. For now, only works with the "url" parameter of an URL. It would be easy to accommodate others, but I don't know of any other parameters a redirect URL would use to refer to the original URL. If you know of any, please contact me.
