"Smart" movement

[Keir Novik]

On the subject of unit movement, I notice that units are reluctant to move
into a destination cell which contains other units.  Giving an order to
move to an adjacent cell does not show this behaviour, and I don't think
cells along a units route are treated this way.

This can easily be seen by giving two units the same destination, where
each unit has to move more than one cell to get there.
