title: tcsh 'ls_colors' not working
body: <p>I am using tcsh as my default shell. However, the LS_COLORS env doesn't seem to work. Here is my related env for ls:</p>
  
  <pre><code>setenv CLICOLOR "true"
  setenv LS_COLORS "di=37:fi=00"
  </code></pre>
  
  <p>Directories are suposed to be coloured white, but the result is they are coloured blue/cyan. Any idea?</p>
