hmm.  instead of patching here and there, what's stopping us
from doing it the right way?  I'd prefer something like:

    import code

    class myCLI(code.InteractiveConsole):
        def displayhook(self, data):
            # non-standard display hook
            print str(data)

    sys.setcli(myCLI())

(in other words, why not move the *entire* command line interface
over to Python code)
