Ok I see this is bash syntaxes.

In that case it works, but I see

But on the GNU emacs repository which is reasonable old (has about 130
000 commits) and is around 700 MB, your command gives:

Which is precisely what you said.


What did I do wrong in my test repo?

Which I generated via the following script


git init
echo "First" > test.org
git add test.org
git add create.sh
git commit -a -m "First commit"
echo "Second" >> test.org
git commit -a -m "Second"
echo "Third" >> test.org
git commit -a -m "Third"
echo "Forth" >> test.org
git commit  -a -m "Fourth"
echo "Fifth" >> test.org
git commit  -a -m "Fifth"
echo "Six" >> test.org
git commit  -a -m "Six"
