Comment 4 for bug 1624216

If there are 500 or less horses (or whatever the cap is), then each horse unit represents one horse, as it does now. Only when there are more horses than the cap would it start assigning horse units to represent 2+ horses.

Remember, I am at best an average programmer. If I can whip up pseudo-code in under five minutes, I'm sure the widelands team can handle it in their sleep.
