The obvious solution is for parser.c to provide a G_terminal_required()
function and for modules which need a terminal to call it before calling
G_parser(). This information can then be made available to gui.tcl.

The other side of the coin is for modules which don't absolutely /need/
a terminal to stop assuming that there is one. I.e. no gratuitous use of
the terminal by modules which are essentially useable without one.
