  a number counts as a prefix arg.
  
  To kill a whole line, when point is not at the beginning, type \
! \\[beginning-of-line] \\[kill-line] \\[kill-line].
  
  If `kill-whole-line' is non-nil, then this command kills the whole line
  including its terminating newline, when used at the beginning of a line
  with no argument.  As a consequence, you can always kill a whole line
! by typing \\[beginning-of-line] \\[kill-line].
  
  If you want to append the killed line to the last killed text,
  use \\[append-next-kill] before \\[kill-line].
