Hmm... I tried as you said, but it seems to lose history.
In the below example, after rewriting there must be two commits for
'b' file but only one exists.
~$ git init filter-branch2
Initialized empty Git repository in
/home/nori/mysrc/test/git/filter-branch2/.git/
~/filter-branch2$ cd filter-branch2
~/filter-branch2$ echo 1 > a
~/filter-branch2$ echo 1 > b
~/filter-branch2$ git add a b
~/filter-branch2$ git commit -m 'first'
[master (root-commit) ae2b5fd] first
2 files changed, 2 insertions(+)
create mode 100644 a
create mode 100644 b
~/filter-branch2$ echo 2 >> b
~/filter-branch2$ git add b
~/filter-branch2$ git commit -m 'second'
[master a32b84e] second
1 file changed, 1 insertion(+)
~/filter-branch2$ git filter-branch --index-filter "git rm --cached
-qr -- . && git reset -q -- b"
Rewrite a32b84ed7cec5686e43a47195dfa8114f83619f3 (2/2)
Ref 'refs/heads/master' was rewritten
~/filter-branch2$ git log -- b

first
Am I doing something wrong?
