It might or might not be an isatty() check (it's actually a bit more
complicated, there's -i and various other things to take into
account), but it hardly matters -- Python already has well-defined
logic for deciding whether it should launch an interactive REPL or
not. If we were going to do this, we'd keep that logic in place while
swapping out the actual start_a_REPL() call with something else. There
might be showstoppers here but I don't think this is one of them :-)
