title: ANSI color in git is not displayed correctly
body: <p>Recently, I switched to SLES 11. I found a problem for git command. All the ANSI color could not be rendered. Instead, it shows the ANSI code like this:</p>
  
  <p>*<strong>ESC[33m</strong>*commit 0a02124a0fd85c1f0094bcdf15bac1645e3c8630ESC[m</p>
  
  <p>note: the ansi color in 'ls' works very well.</p>
