IF has multiple stack effects, its a compiler word. When
called as part of the compiler, it leaves an address on
the stack, when called at runtime it consumes a flag.
I have no good idea to document this yet.

btw: the sleep word takes now a parameter which contains
the actual sleep mode and I checked in the timer interrupt
in forth - democode. Nothing exciting but hopefully useful
