title: bash autocompletion: add description for possible completions
body: <p>Is it possible to make bash auto-completion look like in Cisco IOS shell?</p>
  
  <p>I mean to add short descriptions for each completion, like this:</p>
  
  <pre><code>telnet 10.10.10. (TAB Pressed)
   10.10.10.10 - routerA
   10.10.10.11 - routerB
  </code></pre>
  
  <p>where 10.10.10.10 and 10.10.10.11 are possible completions 
  and routerA &amp; routerB just descriptions (not to be executed).</p>
  
  <p>I know that bash can complete commands with "complete -W", but is it able to print descriptions for them?</p>
