[Bug report] git fetch/push fails from sub-directory

Hi,

I found a bug in git fetch, with local repositories.
git fetch works fine from the root directory, but it fails when called 
from deeper into the file tree of the repository.

git push fails the same way.

The bug is on 1.7.7.rc2 and on master.

mkdir repo1
cd repo1
git init .
mkdir d
touch d/f
git add d/f
git commit -m'initial commit'
cd ..
git clone repo1 repo2
cd repo2
git fetch ../repo1	# OK
cd d
git fetch ../../repo1	# failed

fatal: '../../repo1' does not appear to be a git repository
fatal: The remote end hung up unexpectedly
