For the new initialization code I was going to write after 5.0, I was
planning on implementing this. What I had planned was to use xterm by
default but allow users to set their own term program using an
environment variable if they want. I figured that since grass requires X
windows to run (required by d.mon) then this was a safe assumption to
make.

For grass5 -tcltk the GUI would start and it would create an xterm for
the grass shell. It would also provide a button to create another shell
if the first one is closed. I have tested this long ago and I can launch
the xterm from tcltkgrass.

For grass5 -text we can leave it as is but I was planning that the user
would not be allowed to start the GUI from this shell. They would have
to quit and run grass5 -tcltk. That is, the tcltkgrass command would
disappear.

Do you think this is feasible?
