I'd be more worried about triggering it via the config. E.g.:

  git config branch.autosetupmerge always
  git branch -f foo foo

Should the second command die? I admit I'm having a hard time coming up
with a feasible reason why anyone would do "branch -f foo foo" in the
first place. I just don't want to regress somebody else's workflow due
to my lack of imagination.
