System Information
Windows 10 x64

Blender Version
Broken: Blender 2.79 5bd8ac9

Short description of error
Negative values for texture map options (such as scale and offset, -s and -o, respectively) are broken. I think the issue is that negative values get parsed as options (because of the b'-' check), being added to the map_options dictionary as their own key instead of as a value in the following loop:

      map_options = {}

      curr_token = []
      for token in img_data[:-1]:
          if token.startswith(b'-'):
              if curr_token:
                  map_options[curr_token[0]] = curr_token[1:]
              curr_token[:] = []
          curr_token.append(token)

Import OBJ (note the negative values in the .mtl file)
Take a look at the offset and scale values in the texture panel, as they get default value whenever there is a negative value
