Need to be able to have unit do nothing when on city
I have a unit, my only military unit, on a city. I also have a settler there and a barbarian nearby. So I need to keep my unit there.
However, the game does not give the option to "do nothing" or "fortify" when my military unit is on a city. The only option is to garrison. But I don't want to garrison. If my game were more involved, I might forget that I really wanted to move the garrisoned unit.
I can see no reason why a military unit on a city should not be allowed to do nothing. Please allow this option in a patch.
