git blame: "Not Committed Yet" with clean WD

[Ephrim Khong <dr.khong@gmail.com>]

Hi,

for files that contain windows line endings in a repository with 
core.autocrlf=input, git blame will show lines as "Not Committed Yet", 
even though they were not modified.

Example:

--
git init
git config core.autocrlf false
echo "foo" > a
unix2dos a
git add a
git commit -m "initial commit"
git config core.autocrlf input
git status
git blame a
--

Output:

--
Reinitialized existing Git repository in /.../testblame2/.git/
unix2dos: converting file a to DOS format ...
On branch master
nothing to commit, working directory clean
On branch master
nothing to commit, working directory clean
00000000 (Not Committed Yet 2014-02-13 10:02:43 +0100 1) foo
--

Is there an easy way to work around this; is this desired behaviour or 
mor a bug?

Thanks - Eph
