Specific OBJ file can not be displayed correctly in r76 or later.

[cx20]

Description of the problem

I was not able to display the Gophe 3D model in the obj file.

-> OK : three.js(r73) + MTLLoader.js + OBJMTLLoader.js (http://jsdo.it/cx20/OQ5X)

-> NG : three.js(r76) + MTLLoader.js + OBJLoader.js (http://jsdo.it/cx20/cblg)

-> NG : three.js(r79) + MTLLoader.js + OBJLoader.js (http://jsdo.it/cx20/gxsj)

Gopher 3D model has reduced the number of vertices in the following procedure.

1. open a gopher.blend file in Blender 2.72. (see: https://github.com/golang-samples/gopher-3d)
2. reduce the number of vertices of the model.
3. export to a gopher.obj file

That OBJ file was not properly exported (from Blender).
Here is the fixed version (with 3DS Max) and open with THREE r79:

Is this the OBJ file exporter problem? (from Blender)

-> OK three.js(r79) + MTLLoader.js + OBJLoader.js (using modifed obj file) (http://jsdo.it/cx20/erfU)

I was modifying the file as below, it is now successfully display.

gopher.obj (before)

l 7472 7351
l 7351 7473
l 7774 7707
l 7707 7775

gopher_modified.obj (after)

# l 7472 7351
# l 7351 7473
# l 7774 7707
# l 7707 7775
