Further down, the manual says:

   `C-S-backspace' (`kill-whole-line') kills a whole line including its
 newline, regardless of the position of point within the line.  Note
 that many text terminals will prevent you from typing the key sequence
 `C-S-backspace'.

I'd rather not go hunting for a new key for this command, for the reason
that Glenn gave.
