title: Ctags doesn't display line number with iterm2
body: <p>I switched to iterm2 on my Mac last week. However I found there was an issue when I used cscope with iterm2. The following is the screenshot of the good and bad case. </p>
  
  <p>Good case: Use cscope with Mac default terminal

  <p>Bad Case: Use cscope with iterm2 terminal

  <p>In the bad case, there is no file and line numbers. I am using OSX 10.10.2. Could anyone tell me what's the issue here?</p>
