Ah ok, I'm using Emacs-23 here, and was pulling trunk from bzr but it
was taking a long time, so I just decided to email the fix.

By being reset, I mean I have a hook 
(add-hook 'sh-mode-hook '(lambda () (setq indent-tabs-mode nil)))

I open a sh file, and when I look at the value of indent-tabs-mode,
it's t.

It may be something else that's borking it, but it works fine in other
modes (java, c++). Is there a way to instrument a variable so that I
can see when it gets changed?
