 Hide Google Redirects 1.0:
 -  Hide Google Redirects from view so that you can see the true URL you're
    visiting (and easily copy/paste it). Fully compatible with Google Personal
    Search History.

// @name    Hide Google Redirects
// @namespace   http://www.cs.toronto.edu/~james/google
// @description Hide the Google Redirects from view so you can see the true URL you're visiting. Fully compatible with Google Personal Search History.
// @include http://*.google.*/*
// ==/UserScript==

/* THE PLAN:

1. Goal:     We want users to be able to copy URLs from search results and
             see the true URL they're visiting
   Solution: Get rid of Google's redirects.

2. Goal:     We want Google's personal search history to still work.
   Solution: Notify Google in the background using an XMLHttpRequest when you
             left click, right click, or use the keyboard to select a search
             result.

3. Goal:     We don't want to mess with Google's Revenue Model
   Solution: Don't mess with the redirects for Google ads. Instead, we do some
             sneaky tricks to play with the address bar. This doesn't fix
             copy/paste for Google ads, but it's the best we can do without 
             messing with Google's Revenue Model. As Sergei says, 
             Don't Be Evil. ;)
