2/21    Why does it seem to me that all text files that come to me from
        emacs users use spaces in place of tabs in many places. This is really
        annoying. Does emacs replace spaces with tabs or what? -vim user
        \_ You can fix it with "unexpand -a".
        \_ this can be toggled on or off.  personally I prefer spaces to tabs,
           especially in multi-user environments where people use different
           tab settings.
                \_ Like the motd?
