      Is it for every filetype (including c, html, etc.) or only for some of them
      (such as help, which is set by a modeline)?

      Modelines are intentionally disabled for the root account starting at
      patchlevel 7.0.237 (see http://ftp.vim.org/pub/vim/patches/README and search
      for 7.0.237). This is how I enable them even for root:

      if exists("+modelines")
      " the following is required because of SuSE's paranoid /etc/vimrc
      " and to force 'modeline' on even for root in Vim 7.0.237 and later
      set modeline modelines=5
      " the following disables a dangerous modeline in one helpfile
      if has ('autocmd')
      au BufReadPost ada.txt setl nomodeline ft=help

      Beware that obnoxious modelines have been spotted time and again. The most
      dangerous options are disabled in them, but maybe some dangerous ones have
      been mistakenly allowed: if you enable them for the superuser, you're on your
      own. You may get no problems at all, but if bugs bite you, don't say you
      weren't warned.

      Also: Since you mention root and su, I assume you're on a Unix-like OS, but
      which one? (if Linux, which distro?) And what Vim/gvim version are you using?
      Please paste the first few files of the output of ":version". Only up to
      "Features included (+) or not (-)" ought to be enough.
