bug#29430: 26.0.90; C-M-backspace is undefined

[Devon Sean McCullough]

C-M-DEL and ESC C-DEL should both run the same command.

<C-M-backspace> is undefined

ESC <C-backspace> (translated from <escape> <C-backspace>) runs the
command backward-kill-sexp (found in global-map), which is an
interactive compiled Lisp function in ‘lisp.el’.
It is bound to ESC <C-backspace>, ESC <C-delete>.

                Peace
                        --Devon

P.S. Perhaps a missing translation?

M-DEL (translated from <M-backspace>) runs the command
backward-kill-word (found in global-map), which is an interactive
compiled Lisp function in ‘simple.el’.
It is bound to <C-backspace>, M-DEL.
