I would also love to have right click show you the path instead of moving you, and require a second click to confirm and move.
Yes, or again to use civ4 as an example, right click down shows the path, right click up travels the path. Simply press esc or right click up on the starting square to cancel travel. This would especially be of value since there is no way to predict the path to be taken, and a longer path through forests is often traveled rather than a faster path around them.
