git blame vs. directory symlinks

Hi, list!

OS X 10.6.4
git version 1.7.2.2

Another bug with symlinked directories.

The git blame works correctly for the symliked files, displaying the
history for the symlink source.

However, if the symlink is not the file itself, but a directory in
path, git blame reports the file as "not committed yet".

See minimal example below.

HTH,
Alexander.

mkdir repo && cd repo
git init
mkdir alpha
echo "one" > alpha/file.txt
git add .
git commit -m "initial commit"
echo "two" >> alpha/file.txt
git commit -a -m "updated alpha"
ln -s alpha beta
git add .
git commit -m "beta symlink"

git blame alpha/file.txt

git blame beta/file.txt
