I find it hard to see (null (file-exists-p (dired-get-filename)))
as anything but a bug; if -b didn't put the filenames in the right
form, dired should have done so.
I am, however, very grateful to you for setting me on the right
path. My problem was code in dired-insert-directory that reformats
filenames if it does not find b in the listing-switches. Your message
put me on the right track and I have solved the problem. Thank you.
What I am working with is a substantially revised dired, e.g.,
/Users/diffie/system/emacs/local/dired-mods:
dr-x 10 29Oct12 17:10:33 dired-sort-halves.el
dr-x 16 27Oct12 18:16:51 dired-sorting.el
-r-- 2006 22Apr09 07:41:09 directory-needs-reversion-p.el
-r-- 4714 7Feb12 20:19:43 dired-add-entry.el
-r-- 418 20Jun06 22:16:47 dired-add-file.el
-r-- 939 18Mar07 21:06:53 dired-add-zero-in-filename.el
-r-- 594 30Nov11 11:06:45 dired-approximate-position.el
-r-- 231 7Feb12 19:58:01 dired-at-headerline.el
in which there are numerous format switches. (Anyone who is
interested, is naturally welcome to it; I haven't compared it with
dired in later versions of Emacs.)

My dired doesn't depend on ls. I does use it at present but I
think directory-files would do just as well.
Thanks again,
