Units in formation ignore stop-command

[elexis]

Reproduce:

1. Select 2 or more units (they are in formation by default)
2. Order them to move/attack somewhere
3. Order the stop command

After stopping briefly, they will continue their last command instead of actually stopping. If you press stop again, they do.

This bug is reproducible with both a18 and svn.

Doesn't happen without formation. Only seems to occur with longpaths.

With r17163 but not a18 there will also be a follow-up bug: Reproduce:

1. Enable pathfinder overlay
2. Select 2 or more units (they are in formation by default)
3. Order them to move/attack somewhere
4. Order the stop command twice
5. Order them to move somewhere

You will notice that the resulting longpath for 5. doesn't start at their actual position but near the goal of their previous cancelled path.
