One solution would be to add a new function to parser.c which an
application can use to indicate that it requires a terminal, e.g. 
G_i_need_a_terminal().

The generate_tcl() function would propagate this information so that
run_cmd would know that it needs to run the command in a terminal.

A Tcl/Tk version of the Vask library would be a useful addition.
