emacs in python mode does the correct thing, says the styleguide.

It's the intended behavior.  I think it generally helps you understand
what construct the continuation is part of.

What you do instead is leave the open paren as the last thing on the
line, and then everything else indents one indentation level to the
right.  E.g.

    def __init__(self, width, height,
                 color='black', emphasis=None, highlight=0):
        if width == 0 and height == 0 and \
           color == 'red' and emphasis == 'strong' or \
           highlight > 100:
            raise ValueError, "sorry, you lose"
        if width == 0 and height == 0 and (color == 'red' or
                                           emphasis is None):
            raise ValueError, "I don't think so"
        Blob.__init__(
            self, widt, height, color, emphasis, highlight)

    def ReallyDescriptiveLongNamedGraphicalWidgetWithBellsOnIt(
        self, arg1, arg2, arg3,
        arg4, arg5, arg6):
        some_stuff()
