I mean, this is the documentation of --ff-only: With `--ff-only`, resolve the merge as a fast-forward when possible. When not possible, refuse to merge and exit with a non-zero status. So if you do `git merge --ff-only` you are telling git: "I want you to exit with an error when the fast-forward is not possible". If you do: % git merge --ff-only fatal: Not possible to fast-forward, aborting. That "aborting" part is redundant; we know `git merge` should abort if the fast-forward is not possible, we explicitely told git to do that. Moreover the "fatal: " prefix also indicates that git aborted. Then you have "Not possible to fast-forward", which if memory serves well should be in lowercase (altghough can't find that in the guidelines). "unable to fast-forward" is simply a more succinct way of saying "not possible to fast-forward". Sure, we are not explaining why, although I can't think of any other reason why we could not fast-forward. > Perhaps something like: > > "Can't merge X with Y, in --ff-only mode, would need to create a merge commit", tip_name I don't think die() messages should be that big, how about? branches diverged, can't fast-forward -- Felipe Contreras
