seeing double

I've removed the kludge from the console that causes the print function to
return None instead of the normal string.  It really bothers me when I'm
playing with print that it behaves differently in the console from a script.

The only time you need the print command in the console is when you are
printing multiple items at once.  When you are only printing one item you
can just type the item

    O>> x=6
    6
    O>> x
    6
    O>> print x
    6
    6
    O>>

Try this out when you get your hands on it.  See if you agree.
