bug#2213: (Non)optional arg in kill-whole-line

[Arni Magnusson]

Hi there,

I am using the 'kill-whole-line' function from the 'simple' library, 
noninteractively. According to the function definition and documentation, 
the 'arg' is supposed to be optional, so I was expecting

  (kill-whole-line)

to work, but it crashes with the message:

  Wrong type argument: number-or-marker-p, nil

My current workaround is to use (kill-whole-line 1). I have tested this in 
GNU Emacs 22.3.1.

Thanks,

Arni
