Well, correct Anton, UVMapper doesn't fix this. Deep Exploration does, but in the process it reorders the vertices. It puts each related vertex set together with its facets under the group, but this is no good. The process would be simple enough: Collect all unique groups (g blah) and then move duplicate groups under the first, minding material assignments (usemtl) - which can extend beyond groups. Then do the same for material assignments for each group.

C makes it easy to shoot yourself in the foot. C++ makes it harder, but when you do, you blow your whole leg off.
