Thanks.  I didn't know it had life. :)

I just made the below hack. Add it to your ~/.emacs file.  Then, restart
emacs and, C-x y will do what you ask (I think).  There's probably a
better way to do it:

Matt Flaschen

(defun kill-entire-line ()
"Kills the whole line, including terminating newline, and moves the
cursor directly down"
(interactive)
(next-line 1)
(save-excursion
  (previous-line 1)
  (beginning-of-line)
  (kill-line 1)))

(global-set-key [?\C-x ?y] 'kill-entire-line)
