The non-interactive datum parm bit isn't ready yet, so no TclTk changes
to worry about right now.


This is ready:

  g.proj -c proj4=+init=epsg:$epsg_code location=$epsgLocation

can now be:

  g.proj -c epsg=$epsg_code location=$epsgLocation

But you will still get prompted for transform parms if needed.


Once the datumtrans= list + selection option is working there will be
some TclTk'ing required to take advantage of that.
