No I'm not. Linus's suggested check is "git checkout will refuse to switch
AWAY from a detached head unless the SHA1 of the detached head exactly
matches some other branch."
My question is what use is that? In exactly the situation you describe HEAD
doesn't match a branch.
git checkout v1.0.0
HEAD after that doesn't match any branch so the next "git checkout" will find
that HEAD doesn't match any branch and will refuse to switch away. Why? A
checkout in this case isn't dangerous at all.
Of course I could still be misunderstanding. If Linus meant "refuse to switch
AWAY from a detached HEAD unless the hash of the detached head exactly
matches some other ref", I would be less confused.
