[Gmsh] Marking metis partition edge as distinct physical region.

I'd like to combine gmsh's physical entity marking and metis implementation
to produce partitioned unstructured finite element meshes all set up to be
imported by fenics for a Domain Decomposition project I am working on.
I have been fighting with this for a couple days now, and it seems that all
that is lacking is to get the ragged edge created by the paritioning marked
as a series of elements of type 1 (edges) with distinct physical entity
number. Ie, the .msh files should contain element entries that look like
1 1 4 1 3 1 1 2 3
2 1 4 1 4 1 1 3 4
For two edges in partition 1 of a 2D triangular mesh.
Is there any way to accomplish this? I have thought of one approach as I
write this - maybe use the element location to add points to a new geo
file, extrude the points, and mark them. I don't have a way to get at just
the vertices lying on the ragged partition edge though...
