Thanks for the correction. I see now that I had a few 'auto-mode-alist
lines in my .emacs serving this purpose, but I didn't really
understand them.

Reading the manual, I see that find-file-hooks is now obsolete - will
find-file-hook be obsolete also? What should I replace the following
code with:

(defun my-find-file-hook()
  (let ((fn (buffer-file-name)))
    (when (string-match "latex2rtf" fn)
      (set-variable 'tab-width 4))))
(add-hook 'find-file-hook 'my-find-file-hook)

I use this because a project I'm working on uses a tab-width of 4 for
formatting their c code. I take it that's not ideal, but it's not my
decision. Anyways, all the files are in a directory called latex2rtf,
so this hook does what I need. What is the preferred way to accomplish
this?

Thanks,

Tyler
