#1636: genfromtxt bug with usecols and names=True
------------------------+---------------------------------------------------
 Reporter:  jseabold    |       Owner:  somebody   
     Type:  defect      |      Status:  new        
 Priority:  normal      |   Milestone:  Unscheduled
Component:  numpy.lib   |     Version:  1.5.0      
 Keywords:  genfromtxt  |

 {{{
 from stringIO import stringIO
 import numpy as np
 #np.__version__
 #1.5.0
 s = StringIO("col0,col1,col2,col3,col4\n0,1,2,3,4\n0,1,2,3,4\n0,1,2,3,4")
 arr = np.genfromtxt(s, names=True, usecols=(0,2,4), delimiter=",",
 dtype=['int','int','int'])
 arr.dtype.names
 #('col0', 'col1', 'col2')
 }}}

 Interestingly in trying to reproduce, I mistyped the dtype and got the
 expected names (but no error on my bad dtype).

 {{{
 arr = np.genfromtxt(s, names=True, usecols=(0,2,4), delimiter=",",
 dtype=['int','int','int','int','int'])
 arr.dtype.names
 #('col0', 'col2', 'col4')

 It also works as expected with dtype=None.
