Feature Request - Disengage battle over time

[mattregul]

Feature Request
I have six Sparrow Men just chilling up in the air, just out of range of my soldiers and archers. My dwarves have been running all around the map with little to no success in dispatching these sinful creatures.

Perhaps after x-ticks, if the target(s) are still alive, disengage for a bit of time?

• Are you able to check if the unit is pathable? (this way large ground battles aren't disengaged)

• If x-ticks have elapsed and neither dwarves or hostile takes damage, take a break?
