[emacs-wiki-discuss] TAB completion in eshell disabled

[Cheng-shan Frank Liu]

Hi, I am using emacs-wiki (Emacs 21.3.1) with Linux Fedora Core 2.

I found that loading emacs-wiki conflicts with the TAB completion 
function in eshell. (But this TAB completion function works fine in the 
shell mode.) Everytime when I hit TAB, the error message shows, 
"Symbol's function definition is void: substitute-env-vars."

Below I attached the emacs-wiki settings I put in my .emacs. When I took 
off the lines, the eshell's TAB completion function was back. Please 
advice. Thank you.
