An user must be able to use Dired with eshell/ls at the
beginning even if s?he doesn't have installed an external
"ls" program.

I) emacs -Q -l em-ls
M-: (progn
      (setq insert-directory-program "foobar-ls"
            eshell-ls-use-in-dired t)
      (dired source-directory)) RET

;; We got an error because `insert-directory-program' was called.
;; Now compare with ls-lisp; in this case `insert-directory-program'
;; is not called.
II) emacs -Q -l ls-lisp
M-: (progn
      (setq insert-directory-program "foobar-ls"
            ls-lisp-use-insert-directory-program nil)
      (dired source-directory)) RET

Looks okay, but (a) please cite the bug number in the commit log
message, and (b) shouldn't this:

> +         (not (and (featurep 'eshell) (bound-and-true-p eshell-ls-use-in-dired)))
                                                           ^^^^^^^^^^^^^^^^^^^^^^

quote eshell-ls-use-in-dired?

Thanks.

bound-and-true-p is a macro, its argument doesn't need quoting. boundp
is a function, its argument does need quoting. Trips me up too.

Ah, I see bound-and-true-p confusingly deviates from boundp by quoting
its argument.  So much for mnemonic value...

Sorry.

Oh, I just meant that I also often get the quoting for
boundp/bound-and-true-p wrong.

https://en.wiktionary.org/wiki/trip_up

    trip up: 2. (transitive) To cause (someone) to commit an error,
trick into a mistake.

google.translate (from english to spanish):
"Trips me up too" ===> "Me dispara también"
I read the second as: "It shoots me too".
