Its value is nil. When I start dired after "$ emacs -Q", it displays:

  ls does not support --dired; see `dired-use-ls-dired' for more details.

Following the instructions in the documentation of `dired-use-ls-dired',
I tried Emacs's own emulation of "ls" by evaluating (in "$ emacs -Q"):

  (setq ls-lisp-use-insert-directory-program nil)
  (require 'ls-lisp)

The original problem shows up with this emulation as well.
