Yeah, and of course this does mean you have to be a little careful with M-backspace (backward-kill-word in Emacs), since it will change your kill ring.

But on other hand M-backspace can be useful too if you want to get just part of a line, you can move the cursor to where you want, then M-backspace through words to grab it - if you do M-backspace repeatedly the entire string is pulled into the kill ring until you stop pressing M-BS.
