    docs: gtk_init_check will also fail if the commandline was invalid
    
    The existing documentation seems to suggest that gtk_init_check will
    ignore any failure to parse the commandline arguments, and that its
    return value only depends on its ability to initialize the windowing
    system. That's not true.
    
    Be more explicit to avoid misunderstandings.
