security flaw with smart http

Hi,

I think we found a security flaw with git http smart backend. We are
running git version 1.0.7.4 on our server. Adding random words after the
password and the authentication still succeeds. 

It's very easy to reproduce, say the username is ivan and the password
is the word secret:

% git pull
Username: ivan
Password: secretfoo
Already up to date.

Pull succeeds although the password is wrong! Can someone try to
reproduce with a more up to date git server?
