Allow autostrip keyword in genfromtxt (Trac #1238)

[numpy-gitbot]

Original ticket http://projects.scipy.org/numpy/ticket/1238 on 2009-09-24 by atmention:jseabold, assigned to unknown.

This allows the user to specify whether the whitespace should be stripped from strings in genfromtxt. It does not change the default behavior.

This is how it was handled.

>>> from StringIO import StringIO
>>> import numpy as np
>>> s = StringIO("1/4/2003  ,1.3,abcde")
>>> data = np.genfromtxt(s, dtype=None, delimiter=',')
>>> data
array(('1/4/2003  ', 1.3, 'abcde'),
      dtype=[('f0', '|S10'), ('f1', '<f8'), ('f2', '|S5')])

Now you can do

>>> s.seek(0)
>>> data = np.genfromtxt(s, dtype=None, delimiter=',', autostrip=True)
>>> data
array(('1/4/2003', 1.3, 'abcde'),
      dtype=[('f0', '|S8'), ('f1', '<f8'), ('f2', '|S5')])
