Passing a variable number of arguments to a wrapped function.

[stephen at theboulets.net]

Is there a better way of doing this so that I don't have to go through
every permutation of possible arguments (the example here from the
matplotlib 'plot' function):

def makeplot(self, xvalues, yvalues, linecolor='', linewidth=''):
    if linecolor and linewidth:
        plot(xvalues, yvalues, linecolor, linewidth=linewidth)
    elif linecolor:
        plot(xvalues, yvalues, linecolor)
    elif linewidth:
        plot(xvalues, yvalues, linewidth=linewidth)
    else:
        plot(xvalues, yvalues)
