Please avoid this. 

A tab is  8 spaces, you can't  change it. Well, you can  change it for
you, but  then, files  written by you  will become almost  readable by
other people, or even by you with another tool.

Anyway, you're indenting with spaces, so it wasn't needed. 

There is a  confusion here. TAB is a character. You  can enter it with
C-q TAB in any mode, or with TAB in fundamental mode. 

Most  programming  languages  modes   rebind  TAB  to  an  indentation
function. What you want to  change is the behavior of this indentation
function. (but you understood this from your second post I think)
