emacs -r -Q -l ls-lisp -eval "(setq ls-lisp-use-insert-directory-program t)"
;; Following form must lists just 2 entries in Dired:
M-: (dired (list source-directory "README" "lisp")) RET

;; In fact, it inserts the full content of subdir "lisp".

    Dired w/ eshell: Don't insert subdirs content if dir-or-list is a cons
    * lisp/eshell/em-ls.el (eshell-ls--insert-directory):
    Append '("-d") into 'eshell-ls-dired-initial-args'
    when 'dired-directory' is a cons (Bug#27843).
    * test/lisp/dired-tests.el (dired-test-bug27843): Add test.
