I don't know why you pointed 8.3.2 or 8.4a2. Does init.sh.new work with
another version?

Yes, I agree that the versions of Tcl and Tk can not match. In this case,
init.sh.new is useless :-(

OK, we should change tcl/tk scripts to use GRASS_TCLSH and GRASS_WISH env
vars and add comments to SUBMITTING about this.

	exec tclsh "$0" "$@"	=>	exec $GRASS_TCLSH "$0" "$@"
	exec wish "$0" "$@"	=>	exec $GRASS_WISH "$0" "$@"

Do you agree with this?
