the general solution to this is to force the module not to run in GUI
mode by setting the GRASS_UI_TERM enviro variable.

e.g., from r.digit:

    /* must run in a term window */
    G_putenv("GRASS_UI_TERM","1");

    /* Initialize the GIS calls */
    G_gisinit(argv[0]) ;


then in menu.tcl:
   -command {term r.digit }}


no need for wrapper scripts this way..

I don't use r.reclass so can't really comment on whether that is the
best thing for the module. (is it always interactive in a terminal?)
