Comment(by mikeperry):

 If we decide to prompt, it would say something like "Website
 https://bit.ly/foobar wishes to redirect you to
 https://trac.torproject.org/projects/tor/ticket/3600. Usually this is
 harmless, but in some cases it can be abused through advertising
 partnerships to link your identity on one website to your identity on
 another website. If the ability of these two websites to cooperate to
 track you is a problem, you should click Cancel. Otherwise, click OK."

 Cancel would redirect the user to about:blank, and OK would follow the
 redirect.
