[BUG] vcs_info '%r' doesn't work properly when entered a subdirectory of a git repository through a symlink

[Hong Xu <hong@xxxxxxxxxx>]

Hi all,

The vcs_info '%r' generally works perfect, but when I symlinked a 
subdirectory of the root dir of the git repository to somewhere else, 
and cd from the symlink, '%r' doesn't show the correct value, while the 
git repository can be recognized by zsh.

Example:

mkdir -p tmp/repo/sub
cd tmp/repo
git init
ln -s $(pwd)/sub $HOME/sub
cd ~/sub

Then you will see '%r' is not the root directory of the repo (for me 
it's my home directory basename).

Thanks,
Hong
