How about `visited'? The other precise alternative for that variable 
named is `was-current'.

And considering that our main caller of that hook would be 
`select-window', maybe the current name isn't too far from the mark?

Maybe. Wouldn't an option server this better?

We also allow jumping to a mouse click, and pressing C-u in that case 
becomes more awkward.
