title: Emacs auto-indent tabs instead of spaces
body: <p>I'm about to set EMACS put tabs instead of spaces when auto-indent, but cannot find any clue in the manual. </p>
  
  <p>I tried this:
  <code>(setq standard-indent 8)
  (setq-default tab-width 8)</code>, but somewhy there is still 2 characters instead of 8, and they are <strong>spaces</strong>, not <strong>tabs</strong>.</p>
