This might be something that Gmsh supports, but I don't think we support it
in libmesh currently.

I guess it would depend on the file format definitions for both file types,
which I'm not very familiar with. They are both ASCII files, so have you
tried to simply "cat" them together? Also, what is your ultimate goal here,
just to have a single file for organization purposes?
