UTM coordinates in xgdisplay

I'm not one to bad-mouth GRASS modules, but I've never been able to keep 
xgdisplay up and running long enough to find such a bug!! I hope that sometime
in the future someone is able to take the time to make xgdisplay more robust,
because it is basically a neat little program.

My 2 cents - not necessarily my employer's.
