Face Selection Masking for Painting overlaped by the texture Doing the Piero Course, when it comes to paint the textures in the model direct in the Texture Paint mode, when setting the Face Selection Masking for Painting, the overlaping wire frame won't show.

Is there a additional configuration that I'm missing so I can paint with these wire outlines? The .blend file is in this link.

Edit: Packed .blend file with textures and updated the link.
I'm sorry, but since the Blender 2.73 version release you can't display the wire outlines while painting. 



''Paint mask selection now only shows selection boundary (so you can better see what you are painting)'', as you can read in this manual: http://wiki.blender.org/index.php/Dev:Ref/Release_Notes/2.73/Painting
