Surviving falls by firing both barrels of the boomstick at the ground before landing

Easily tested and reproduce-able in the paris level. Jump out the window from the second story of the building with all the office chairs in it, near one of the trader pods. It's high enough that if you actually *jump* out the window, you take damage. If you have the boomstick, you can fire at the ground with both barrels. It launches you back slightly before landing. You don't take damage when you hit the ground.

Not sure if this is really considered a glitch or not, but it seems like it could become a minor exploit if tripwire releases maps with higher falls.
