Do I assume correctly that `git for-each-ref HEAD` does nothing, successfully,
for the very same reason?
If so, I wonder if this should be somehow reflected in the docs.
I mean, I have always maintained an impression that things like HEAD,
ORIGIN_HEAD, FETCH_HEAD etc are also "refs" - because they, well, reference
commits or branches.
The gitglossary manual page of my Git 2.30.2 states that
| ref
| A name that begins with refs/ (e.g. refs/heads/master)
| <...>
| There are a few special-purpose refs that do not begin with refs/.
| The most notable example is HEAD.
which suggests that HEAD is a ref.
