I should add, I think I initially saw the problem as Andrew put it, that the
array of char*'s was like a 2d array so in order to "return" it I needed to
pass a pointer to a 2d array i.e. char***. But then realized I could skip
that and just do pointer copies instead. Bleah.. give me a nice class foo&
any day..
