Bug? Unexpected outputs of git pull on stdout v.s. stderr

Hello,

git --version -> git version 1.7.9.5 on linux

A 'git pull' operation exits with 1 (which is normal) but generates the following output and error flows:

stdout: Auto-merging c/makefile CONFLICT (content): Merge conflict in c/makefile Auto-merging c/x_color.c Auto-merging c/x_export.c CONFLICT (content): Merge conflict in c/x_export.c ... CONFLICT (content): Merge conflict in c/x_line.h Automatic merge failed; fix conflicts and then commit the result.

stderr:
From /home/malaise/ada
* branch            Xft        -> FETCH_HEAD

With option -q the Error flow is empty and the Output is as before.

I would expect that the text:

is part of stdout and suppressed with option -q

And that the message:

is part of stderr (and kept with option -q).

Or did I miss something? Thank you.
