title: Buffer cycling in Emacs: avoiding scratch and Messages buffer
body: <p>Hi I have turned on buffer cycling placing following commands in my .emacs </p>
  
  <pre><code>(global-set-key (kbd "&lt;C-tab&gt;") 'bury-buffer)
  </code></pre>
  
  <p>But while cycling how do I avoid cycling through the Messages and the scrratch buffers which
  are always present in any emacs buffer list. I never use those buffers and become an eye-sore 
  when cycling through my buffer-list</p>
