Having trawled the Blender forums, a great number of Blender folks had requested exactly the same thing. Fault reports received feature, not bug, responses. Apparently, cycles triangulates everything during the render process, so by the time the wireframe node gets to act, the mesh it sees is only triangles, so it's stuck with that.
Workarounds appeared to be to use a reset UV map where every facet was an island (whatever that means, possibly that every single texture edge gets duplicated so shading groups aren't regarded as contiguous). It might just be a matter of using the rendered UV map as a mask, since the wireframe node doesn't do what anyone expected it to.
Verbosity: Profusely promulgating Graham's number epics of complete and utter verbiage by the metric monkey barrel.
