I just tried this, but not sure its a fair test:

1) Put the two lines you suggest as sole entries in lisp.el then start
   a fresh emacs. (emacs -q -no-site-file -bg midnightblue -l ./lisp.el -l 
./vi-list.el)
(vi-list.el is some plaguerized code that allows one to display a
   buffer as if vi's `list' command had been run on it. (showing
   ^I = tab $= newline)

   Set background different than usual so I could keep track of which
   emacs has the new code.

2) Started a second emacs (emacs -q -no-site-file -l ./vi-list.el)
   (without the new code)

Ran C-x h then C-M \ on both  Then saved the results as:
shellt1.sh (new code)
shellt2.sh (no new code) 

Both files are attached.
invoking vi-list shows the tabs are gone, but strangely the code is
formatted almost the same.  The deepest indentation being only 2 spcs
different. I would have expected to gain quite a lot more.

The source file looks like:
Cat shell-script.sh
if [ ];then
if [ ];then
case $opt in
t) cmd
lf  [ ];then 
cmd
fi
;;
h) cmd
if [ ];then
case $otheropt in
a) cmd
if [ ];then
cmd
fi
;;
b) cmd
::
esac
fi
 esac
if [];then
cmd
ii
fi
fi
