title: emacs unable to find cscope database?
body: <p>I have a very strange problem, which just appeared with the new builds and my cscope command to generate the db didn't change(cscope -b -q -i ). I can see the results with 'cscope -d' on the terminal, so I know the cscope.out is correct. However if I use cscope from emacs(v23.2.1) it shows me no results:</p>
  
  <pre><code>Finding symbol: find_best_path
  
  Database directory: /workspace/project_large/
  -------------------------------------------------------------------------------
  cscope: no source files found
  
  -------------------------------------------------------------------------------
  
  Search complete.  Search time = 0.11 seconds.
  </code></pre>
  
  <p>And when I run 'cscope -d' from /workspace/project_large/ it gives results.
  I am scratching my head here. Any insight into how to find the root cause would be helpful.</p>
