It'd be really nice to be able to right-click and copy-paste clean URL.

In some cases people don't need the URL in the browser, and don't need to open the actual page (or pdf document). Sometimes one need the URL itself - to send it via e-mail, copy into a command line, or anywhere else.

And in all of these cases it is a pure time waste - going to website (or starting PDF download), or cleaning up the URL, because google deceptively substituted it on a right-click. Or monkeying around with scripts that would prevent Google search from tracking clicks all-together.

And one more thing. Just like the original poster says: people hate not being able to just copy the URL. And every time somebody have to waste time cleaning it up, a little bit of hate towards Google sneaks in.
