Gee.  Well, with the SyntaxError patch, at least the error message
is much better (even though the arrow still points to the wrong place):

    >>> class foo:
    ...     def foo(self):
    ...         pass
    ...    def foo(bar):
      File "<stdin>", line 4
        def foo(bar):
    SyntaxError: dedent does not match any outer indentation level

Not sure why the arrow points there... i would have expected it to
point at the beginning of the line, since it did successfully detect
that the indentation was wrong.  Maybe i'll investigate.
