commit 68ed6dd88ab30b482b70854452b41ee2768ce03e
Author: Cao jin <caoj.fnst at cn.fujitsu.com>
Date:   Tue Jun 23 18:38:19 2015 +0800

    Modify the function: analyze_line, make it more flexible
    
    Modify the function from a fixed delimiter to a variable. So,
    it can be used in more APIs later. Also modified the existing
    callers
