    Remove obsolete comment
    
    The comment probably dated back to when xwidgets supported
    many other GTK+ widgets with other data.  In the current
    implementation of xwidgets, everything that should be freed
    is already freed in `kill_buffer_xwidgets'.
    
    * src/xwidget.c (kill_buffer_xwidgets): Remove outdated TODO.
