bug#3785: 23.0.91; Strangeness involving regexp in directory-files command used on dir of links |

I have files of todo items for various projects and a directory of
links to those files. A simple function to search those files was
skipping over links named "misc" and "emacs". The following function
narrows the problem down. It seems to be a true problem but maybe I'm
doing something dumb? I use emacs-snapshot, 23.0.91.1 but checked
using emacs 22.2.1 from Debian Lenny and same problem occurs. Also
checked with emacs-snapshot started with emacs -Q. Problem is same.
;;; ============================================================
(defun test-links ()
"This narrows down a problem showing in a more complex program."
(interactive)
(setq links (directory-files "~/programming/emacs/debug/links" t "[:word:]"
t))
(dolist (l links)
(insert (format "File: %s\n" (file-truename l)))))
;; Recipe for duplicating strangeness.
;;
;; 1. Set up a directory containing links named: misc, reading, and emacs.
;;
;; 2. Run the above function as follows to get corresponding results.

;; With regexp = :word:
;; File: /home/loydf/daybook/tasks/reading
;; With regexp = :digit::word:
;; File: /home/loydf/daybook/tasks/misc
;; File: /home/loydf/daybook/tasks/reading
;; With regexp = :digit::word:emacs
;; File: /home/loydf/programming/emacs/debug/links/misc
;; File: /home/loydf/programming/emacs/debug/links/reading
;; File: /home/loydf/programming/emacs/debug/links/emacs
