Leg lift's definition is a bit restrictive, though not necessarily unreasonably so. It's just nuclear how much of a separation is needed before it counts.
I'm aliasing raised_leg and leg_raise to leg_lift for now because what's in those fits that wiki.
Leg-up is pretty large though, and undefined. I'm okay with moving it to leg_lift but we might need to loosen leg_lift's definition a little.
