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
