A 2nd Dired call on the same directory must update
the buffer when the wildcards have changed.

emacs -Q -l dired -eval '(dired (expand-file-name "lisp" source-directory))'
M-: (dired (list default-directory "simple.el")) RET
;; Same Dired buffer.
C-x k RET ; kill the buffer.

;; Show Dired buffer with just 'simple.el':
M-: (dired (list (expand-file-name "lisp" source-directory) "simple.el")) RET
C-x d RET ; Same Dired buffer.
