 While developing a plugin I needed to see the transition in roles. This is
 because I am delaying the sending of the new user welcome email until a
 certain role has been set. So I want to see if a certain role existed
 before when setting the new role. If yes, send the email.

 Of course, I could hook on earlier in the actions and cache the current
 user's role, but it would be much easier if the old roles were passed into
 "set_user_role".

 Attached is a diff of the change.
