#509: histogramdd fails on indentical input arrays
 Reporter:  dhuard  |       Owner:  somebody
     Type:  defect  |      Status:  new     
 Priority:  normal  |   Milestone:          
Component:  Other   |     Version:  none    
 Severity:  normal  |    Keywords:          
 Emanuele Olivetti reported the following bug on the numpy discussion list.
 import numpy
 x = numpy.array([0,0])
 y = numpy.array([0,1])
 Warning: divide by zero encountered in log10
 exceptions.OverflowError                             Traceback (most
 recent call last)
 The patch fixes this and adds the relevant test. The fix makes the
 behavior identical to histogram, namely that if min() == max(), the range
 is chosen as [min()-.5, max()+.5].
