Actually, it probably won't work from the autogenerated GUI. At least 
it never has on my Mac. This is another case of the autogenerated GUI 
not parsing arguments with spaces. In this case, the bgcmd=d.rast 
mapname won't work because there is a space. This does work from the 
command line. It also works if you add a raster command from within the 
v.digit settings dialog after starting v.digit.
