title: cscope error when trying to use ctags in vim
body: <p>I have generated ctags for my projects:</p>
  
  <pre><code>ctags -f /home/grae/tags --recurse --langmap=C++:.C.h.c.cpp.hpp.inl --languages=C++ --extra=+q --fields=+iaS --c++-kinds=+p --verbose framework/ modules/ /usr/include/
  </code></pre>
  
  <p>I then added the tags to .vimrc:</p>
  
  <pre><code>set tags+=/home/grae/tags
  </code></pre>
  
  <p>I also temporarily added the following (but have now removed):</p>
  
  <pre><code>set csto=1
  </code></pre>
  
  <p>Now when I try Ctrl+] or g] I get the error:</p>
  
  <p>cstag: tag not found</p>
  
  <p>I shouldn't be using cscope so I'm not sure how this has happened. My current thoughts are:</p>
  
  <pre><code>* cscope on by default
  * something has overriden Ctrl+] and g]
  </code></pre>
  
  <p>Any ideas how to solve this?</p>
