BUG: Siege combat, garrison doesn't surrender

[delatbabel]

I have now been able to reproduce (twice) a bug in a siege / assault combat the garrison doesn't surrender after being broken. Once in Paris and once in Constantinople, both with large garrisons (mostly militia).

Steps to reproduce:

* Move forces to the city.
* Launch assault.
* Win the battle (i.e. break the defenders) without being broken, and without eliminating the defenders.

The remaining defenders should surrender, but this does not seem to occur. I end up in position outside the city again, still besieging, and with the reduced garrison still inside the city. I have to assault the city a second or sometimes third time, in subsequent months, and eliminate the garrison before the city will fall.
