title: Why might my Emacs use spaces instead of tabs?
body: <p>I am trying to diagnose this problem. TAB creates 4 spaces instead of a 4 col TAB like I want. But I don't think it should because <code>C-h v indent-tabs-mode</code> on the buffer in question says it is set to <code>t</code>. When I check my keybindings, TAB is set to <code>c-indent-line-or-region</code>. Does this function ignore my tabs-mode? </p>
