Good. I committed a slight variation to CVS that I think should work 
reliably.

There will still be a problem there, as running g.proj -wf in an XY 
location will print something like 'XY (Unprojected)' to stdout. This was 
originally a design feature, as g.proj -p certainly should print something 
to indicate that the location is XY. But probably g.proj -j (PROJ 
format) or g.proj -w (WKT format) should print nothing as there is no 
PROJ.4 or WKT representation of an XY location. Or perhaps is there a way 
of representing it in WKT? I'm not sure.

I'll think about this a bit more but at the minute my plan is to change 
g.proj so it prints nothing for an XY location if the -j or -w options are 
selected.
