You might want to pinch glade-2 code here, as it provides nice argument
names instead of "argXX" (at least for standard GTK+/GNOME signals).
It uses a hard-coded table, that I had to create manually. That isn't
ideal, but is the best we can do at present. (Or maybe you could put
this stuff into the widget description XML files.)

The code is in gb_widget_write_signal_handler_source() and
lookup_signal_arg_names() in glade/gbsource.c.
