please update from CVS.

now grass-run.sh (lib/init/g-r.src) pauses if the module ends in an
error.

also r.digit has been changed to never use a startup GUI.

r.digit needs a GIS.m Map Display window open to get region info from.

we can work on that, either with a bgmap= option or full bgcmd= like
v.digit.

same issue for r.digit, but I'd rather we leave r.digit alone and focus
on a new v.digit/r.digit replacement (write to ascii file on exit then
feed to "v.in.ascii format=standard" or r.in.poly). I think it is pretty
simple --- but we need to pick a Wx/Gtk Python flavour to move ahead!
