git pull regression?

Hi,

I tested git v1.6.0.3 today and noticed that git pull is
behaving strangely, compared to what I was used to with
v1.5.6.3

It no longer tells me "Already up-to-date." when it used
to, now it simply says nothing.

And when I pulled Linus tree for the kernel this morning 
it downloaded the new commits but git didn't show the 
diffstat.

Furthermore, it kept saying to me 
"Your branch is behind 'origin/master' by 31 commits, 
and can be fast-forwarded"
and git log was not showing the new commits.

At first I thought I had made some mistake with my repo,
but I searched the mailing list and there was a similar
case which was "fixed" after using 'git status' followed
by another 'git pull'. But in my case it did not help.

So I went back to v1.5.6.3 and everything was back
to normal.

After that I made some tests, and v1.6.0 was good
and v1.6.0.1 was bad, but I didn't bisect it
further.

It looks like a regression to me. I can finish
the bisection if people in the list say that
I am not making a mistake somewhere :-)
