#986: Von Mises draws not between -pi and pi [patch]

     Type:  defect        |      Status:  new                        
 Priority:  normal        |   Milestone:  1.3.0                      
Component:  numpy.random  |     Version:  none                       
 Severity:  normal        |    Keywords:  Von Mises, vonmises, mtrand
--------------------------+-------------------------------------------------
 As the following test shows, Von Mises draws are not currently staying
 between -pi and pi (at least on my Mac):

 from numpy import *
 import numpy as np
 import pylab as pl

 for mu in arange(-4,5)*pi/2:
     q=pl.hist((np.random.mtrand.vonmises(mu,1,10000)),50)
     print mu
     raw_input()

 The attached patch makes them do so.
