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.
