[Gmsh] bug (?) in gmsh-1.65

Hello
I wanted to upgrade our lab to gmsh-1.65 today (from 1.60) and we fell on a
possible bug in the UNV exporting functionality.
The attached geo/unv pairs should demonstrate the bug:
exporting a 2D mesh in UNV format includes now elements of type 21 (beam) for
the border of geometry (see carre.geo/carre.unv)
The same happens in 3d. When exporting the tetra mesh generated from the
cube.geo (from the demos directory of gmsh-1.65) in UNV format both the tetra
elements and triangles for the geometric faces of the grid are included in
the exported file.
I must acknowledge that all this doesn't have the feel of a bug, but I have
fallen into it because trying to import with our in-house code the UNV meshes
generated by gmsh-1.65 doesn't give us the same result as with the same
meshes exported by gmsh-1.60.
Thanks.
