Not me.  I am just testing all the functionality available.
Someone added in 2000 a defcustom `eshell-ls-use-in-dired', so 
that you can run eshell-ls to list directories with Dired.

Now i understand why i get this error: the dired support was added
'a posteriori'.

I think an user who want to set `eshell-ls-use-in-dired' non-nil is
likely someone with no external 'ls' installed.
