Hi,
In my repo, I have some symlink to readonly jar, I can't make difftool
between 2 commit
Steps to reproduce :
> git --version
git version 2.17.0
> id
uid=1000(sagoum) gid=1000(sagoum)
groupes=1000(sagoum),5(tty),10(wheel),14(uucp),18(audio),20(dialout),27(video),35(games),78(kvm),85(usb),100(users),104(plugdev),992(android),993(docker),997(vboxusers)
# readonly jar
> ls -l /home/tempogit/jenkins_war
total 510012
