However, thank you for drawing my attention to this passage.  It incorrectly
qualifies the prefix arg as needing to be "numeric".  Any prefix arg, not just a
numeric one, causes `dired' to prompt you for the `ls' switches.  I've filed an
Emacs bug (#6982).  (This doc bug is at least as old as Emacs 20.)
