[Freeciv-Dev] (PR#12836) AI Grabs Allies as City Guards

["Benedict Adamson" <badamson@xxxxxxxxxxx>]

<URL: http://bugs.freeciv.org/Ticket/Display.html?id=12836 >

The function ai_set_defenders considers *all* units in a city as 
potential city guards. It will therefore consider allied units that 
happen to be present, including units owned by human players.

My AI guards (see PR#12781) API manifests this problem by complaining 
that guards are 'being asigned [sic] to foreign city' for the attached 
autogame.
