   The above still is broken.

   And I found another strange behaviour for numpy.fromstring (NumPy 1.10.4).

   import numpy as np
   np.fromstring('1.0, 2.0, 3.0\n', dtype=float, sep=",")
   >>> array([ 1.,  2.,  3.])
   
   np.fromstring('1.0, 2.0, 3.0,\n', dtype=float, sep=",")
   >>> array([ 1.,  2.,  3., -1.])

   If the string ends with a seperator and a line break, a -1.0 is inserted.
