However, "git merge" didn't have an --autostash option, so, when "git pull --rebase --autostash" was called *and* the fast-forward merge shortcut was taken, then the pull failed. This was fixed in commit f15e7cf5cc (pull: ff --rebase --autostash works in dirty repo, 2017-06-01) by simply skipping the fast-forward merge shortcut. Later on "git merge" learned the --autostash option [a03b55530a (merge: teach --autostash option, 2020-04-07)], and so did "git pull" [d9f15d37f1 (pull: pass --autostash to merge, 2020-04-07)]. Therefore it's not necessary to skip the fast-forward merge shortcut anymore when called with --rebase --autostash. Let's always take the fast-forward merge shortcut by essentially reverting f15e7cf5cc.
