[Development] Why there is no Change-Id when I commit in qt4.8?

[liang jian]

    Hi, everyone,
    Recently I pushed two changes to Qt project for Qt5, I want them
also be pushed to Qt4.8, so I change the code in my qt4 repository
(cloned from gitorious.org), and try to commit it, To my surprise, the
commit message doesn't contain the Change-Id (I have copy the
commit-msg to .git/hooks). Do I forget something about setup my
development environment?
