  "An assoc list of command line arguments that should in gtk-initial-argv-list.
This is necessary because GTK and GNOME consider it a fatal error if they receive
unknown command line arguments (perfectly reasonable).  But this means that if
the user specifies a file name on the command line they will be unable to start.
So we filter the command line and allow only items in this list in.

The CDR of the assoc list is whether it accepts an argument.  All options are in
GNU long form though.")
