title: Vim, colourschemes and setting ctermbg doesn't work properly
body: <p>I want to highlight the cursorline in Vim, depending on if I'm in insert mode or in command mode (using it in Gnome Terminal/Gnu Screen on Ubuntu) and some people suggested I should use these commands in .vimrc</p>
  
  <pre><code>au InsertEnter * set nocursorline
  au InsertLeave * set cursorline
  hi cursorline cterm=underline ctermbg=243
  </code></pre>
  
  <p>All of the above commands work fine if I use them in Vim directly (use the settings temporarily until the next restart).</p>
  
  <p>I also load a colourscheme named "wombat" in .vimrc, but there are several problems occurring when using the same commands in .vimrc:</p>
  
  <ul>
  <li><p>If I put the ctermbg-command after loading the scheme (as I should), the scheme is somehow ignored/not loaded/not used or whatever. Meaning, that vim comes up with some standard colours.</p></li>
  <li><p>If I put the ctermbg-command before loading the scheme, the highlighting doesn't work but the scheme is loaded.</p></li>
  <li><p>If I only try to set cterm, then the scheme is loaded, but the underlining doesn't happen. No matter which command comes last.</p></li>
  </ul>
  
  <p>Any thoughts?</p>
