 Agree re: GRASS6, just for compatibility's sake.

 For 7.x, I have removed this kind of "magic" behaviour whenever I have
 encountered it. Apart from anything else, it means that the overwrite
 check has to be performed manually, rather than letting G_parser() do it.

 It's worse for modules which create new maps (import and analysis). E.g.
 it might be desired to add an option to the GUI to automatically add
 newly-created maps to the map display. Obviously that can only work if the
 GUI knows that a map has been created, and what it's called.
