BTW: I'm for driving cautiously instead of idling.
When the oil is cold, lubrication is not as effective. Driving the car gingerly heats up the oil more quickly than idling thereby shortening the amount of time the engine is being lubricated by cold, thick oil. The difference is minor but over the lifetime of the engine it will add up.
