You have bound the backspace function key and the DEL ASCII character
(by default, backspace is automatically translated to DEL).

Try also binding [delete] and "\C-d" (likewise, the ASCII character
to which delete is translated).

I wonder if an alternative implementaton would work: instead of binding
any keys at all, make backward-delete-char-untabify-method buffer local
and toggle its value between `hungry' and the global value.
