[GRASS-dev] updates to grass startup

[Hamish]

when creating a new location from EPSG code an xterm flashes up and then
disappears. This might have some important info/warning/error in it.

I have prepared the following patch, but not applied it as it makes the
script partially interactive. (ie it asks the user to press <enter> to
continue, but times out in 2 minutes [enough time to find a pen and
write down an error])

So not a great solution, but here it is. 

Better? put a pause at end of exec grass-xterm-wrapper:

lib/init/epsg_option.tcl.in:

exec -- $env(GISBASE)/etc/grass-xterm-wrapper -e \
         $env(GISBASE)/etc/make_location_epsg.sh \
         $epsg_code $epsgLocation $locpath >@stdout 2>@stderr; \
         read -t 120

or somehow like that?
