warning: unable to rmdir my/module: Directory not empty

Hi all,

  Does anyone knows where is this warning is coming from:

warning: unable to rmdir my/module: Directory not empty

  I have a git master, an empty branch and a submodule on master.
Switching from master to my 'empty' branch always trigger this
warning. Here are some steps to reproduce the issue (*). I am using a
debian stable system + backports and version is:

$ git --version
git version 1.7.1

Thanks
-Mathieu

(*)
# master
cd /tmp
mkdir test
cd test
git init
touch README
git add README
git commit -mREADME

# submodule
cd ..
mkdir module
cd module
git init
touch MODULE
git add MODULE
git commit -mMODULE

cd ../test
git submodule add file:///tmp/module my/module
git commit -a -m"adding submodule"

# create an empty branch
git symbolic-ref HEAD refs/heads/newbranch
rm .git/index
git clean -fdx
touch EMPTY
git add EMPTY
git commit -a -mEMPTY

# update
git checkout master
git submodule init
git submodule update
git checkout newbranch

This is because submodule deletion is not well supported at the
moment. There has been a lot of discussion how to make git handle
that better but no one implemented it so far. But it's on my ToDo
list, so stay tuned ...
