And the following magic in my ~/.inputrc does the same (and a bit
more) without any source-level changes:

  set convert-meta off
  "\340\163": backward-word               # Ctrl-left
  "\340\164": forward-word                # Ctrl-right
  "\340\223": kill-word                   # Ctrl-Delete
  "\340\165": kill-line                   # Ctrl-End
