Perhaps a better solution than adding `advertised-widget-backward'
is not to bind M-TAB on on graphics terminals at all.

TAB and S-TAB are standard keys to move to next/previous links in modern
GUI applications.

I think this is not a big problem that S-TAB is not available on a tty.
There was no M-TAB keybinding in Emacs for moving to the previous link for
several years until it was installed a month ago, and nobody complained
about this.
