WARNING: s ignored in line [...] #38

What steps will reproduce the problem?

If I am loading .obj files either generated from 3ds max exporter or converted 
by the open asset import library i get the error.
WARNING: s ignored in line [linenumber]

as far as i know s stands for the smoothing groups aka vertex normals in the 
.obj file format.

Got this info from here: http://en.wikipedia.org/wiki/Wavefront_.obj_file
"Smooth shading across polygons is enabled by smoothing groups."

Are smoothing groups not recognized in the exporter?

Here is a link to a obj file causing the issue:

For the purposes of rendering, webgl-loader treats "s" groups like "g" groups. 
In fact, it doesn't really do much, because it uses the available per-vertex 
normals. In other words I'm expecting that, the modeling software that exported 
the OBJ should have already computed the normals.

What do you think?
