produces this error message:

  warning: refname ‘47acbeca3e13a03131a0a7a9a3bd3443e1760d71’ is ambiguous.
    Git normally never creates a ref that ends with 40 hex characters
    because it will be ignored when you just specify 40-hex. These refs
    may be created by mistake. For example,
  git switch -c $br $(git rev-parse …)
  where “$br” is somehow empty and a 40-hex ref is created. Please
    examine these refs and maybe delete them. Turn this message off by
    running “git config advice.objectNameWarning false”
