Virgil Dupras c3838714d5 forth: improve execution model 
My approach with RS was slightly wrong: RS' TOP was always containing current

RS-modifying words: it's impossible to modify RS in a word without immediately

Therefore, what used to be RS' TOS has to be a variable that isn't changed
midway by RS-modifying words. I guess that's why RS is called *return* stack...
