regression in output of git-pull --rebase --recurse-submodules=yes --quiet

Somewhere between 2.13.6 & 2.14.1 there's an output regression. I haven't done a bisect to trace it down further yet.

Specifically, --rebase --recurse-submodules=yes seems to cause --quiet to not be effective anymore.

Full commandline: $ git pull --rebase --recurse-submodules --quiet

In 2.13.6, there is no output, it's quiet as expect.

In 2.14.1, you get: HEAD is up to date. Submodule path '_data/news': rebased into 'a50b763c338161b4621d23e9fa5cd6e11455d6ca' HEAD is up to date. Submodule path 'glep': rebased into 'e1f100ec3ba44ab1672d61cabf4690b355e46158'

Steps to reproduction:
1. git clone --recurse-submodules \
 https://anongit.gentoo.org/git/sites/www.git
2. cd www
3. git submodule foreach --quiet git pull --quiet origin master
4. git pull --rebase --recurse-submodules=yes --quiet

Repeat step 4 for repeated bug output. If you drop the --rebase, then you need to re-run step 3 first.
