Wow. I've had this for so long in my setup that I forgot that this was
removed from vanilla Emacs in Emacs 22. It was always present in older
Emacs releases, and it makes sense (IMO). Please restore the binding of
<C-M-backspace> to `backward-kill-sexp' in the Lisp modes, so others can
benefit from it by default.
This seems to have been a mistake, rather than a deliberate change - or
else it was perversely deliberate. `backward-kill-sexp' IS bound to ESC
<C-backspace>, but it is not bound to <C-M-backspace>. What's that
about?
It is also bound to ESC <C-delete>, but not to <C-M-delete>. Yes, some
systems like Windows (which I use) will not let you use <C-M-delete>.
But that is no reason not to bind it in Emacs for people who can use it.
(Actually, I would probably argue that ESC <C-delete> and <C-M-delete>
should both kill a sexp forward, not backward, i.e., `kill-sexp'. The
<delete> key generally kills forward, in Emacs, as in other apps. But I
don't really care about that. And you'd probably argue that `C-M-k'
would then also be forward, by analogy with `C-k', or some such.)
