stdout vs stderr

Hi, is there a reason why those messages for pull are sent to stdout and for push are sent to stderr?

flo@p3:~$ git pull Already up-to-date. flo@p3:~$ git pull >/dev/null

flo@p3:~$ git push Everything up-to-date flo@p3:~$ git push >/dev/null Everything up-to-date

I am regularly trying to build automatisms around git and typically i redirect stdout to /dev/null in the hope that when something goes wrong i see error messages on stderr. This does not work for e.g. push for obvious reason.
