Hi,
Since 2.26.0 a simple "git rebase" fails to fast-forward a
branch, reporting "error: nothing to do."
It started to work again after removing my gitconfig. I've
reduced it to the following:
git init foo; cd foo
git commit --allow-empty -m foo
git commit --allow-empty -m bar
git checkout -tb foo
git reset HEAD~
git -c rebase.abbreviateCommands=true rebase
