I had originally intended to add a kind of `hungry-delete-mode`, because
sometimes this type of deletion is useful (e.g. for some programming
modes).
While `cc-mode` already have it, it's only "exclusive" for `cc-mode`
modes.
This new command was more of a kind of `c-hungry-delete-forward` than a
`backward-delete-char-untabify`.
I wasn't sure if it would be worth moving those cc-mode commands for
general use, or make/move the `hungry` feature from
`backward-delete-char-untabify` to be used generally.
