Re: [PATCH v6] Add new git-related helper to contrib

This doesn't make any sense:

--- cd /tmp rm -rf blame

git init blame cd blame

cp ~/dev/git/COPYING COPYING git add COPYING git commit -m initial

sed -ne 120,140p COPYING >EXTRACTING git add EXTRACTING git commit -m second

git log --oneline git blame -C EXTRACTING

echo >>COPYING git commit --amend -a --no-edit

git log --oneline git blame -C EXTRACTING ---

Why would the first instance find the blame in commit #2, and the second one at commit #1? If anything, the second instance should have more trouble finding the original commit.
