I'm trying to hack the following elisp code to delete the buffer it
has just left when it goes to the new buffer.  This code is for
enhancements to dired to go up and down directories easier.


(defun dired-up-directory ()
  "Find .., switching to its buffer if it exists"
  (interactive)
  (let* ((target-dir (parent dired-directory))
	 (target-dir-entry (assoc target-dir dired-dirs-alist))
	 (target-dir-buffer (car (cdr target-dir-entry))))
    (cond (target-dir-entry
	   (cond ((memq target-dir-buffer (buffer-list))
		  (switch-to-buffer target-dir-buffer))
		 (t (setq dired-dirs-alist (alist-delete target-dir-entry
							 dired-dirs-alist))
		    (find-file target-dir))))
		  (t (find-file target-dir))))
)


I'm trying to use (kill-buffer (previous-window)) which worked in
another function to kill the buffer, but nothing happens now.  I've
tried placing it right after the (interactive), just before and after
(switch-to-buffer ...), and at the very end after (t (find-file
target-dir)))) but nothing happens.  It all loads fine, but it go...
blah!

No while I'd like a fix for this problem, I'd also like an explanation
of WHY it didn't work.  Thanks for your time and effort...
