As someone who enters active runways most days (in a vehicle) it's very interesting to note the differences between military and civillian controllers, indeed the difference between individual controllers. Among the older ones if he was trained in the USA he will say check gear down and locked but if he was trained in UK he will say check 3 greens. I often hear confirm you are clear of the runway or clear off the runway, never vacate the runway. Clear for engine start is commonly heard and as I type I just heard cleared to FL 150. After that little lot my guess is that wherever you go in the world you'll hear something different / non standard!
