Not good, 'git branch' is a porcelain (user facing) command, so it
output may change; e.g. '*' could be replaced with '•'. For example
output for detached HEAD had changed!

This does not work for detached HEAD, but perhaps you don't need
to worry about this.

  $ git rev-parse --symbolic-full-name HEAD


  $ git checkout HEAD^0
  Note: checking out 'HEAD^0'.

  You are in 'detached HEAD' state. [...]
  $ git rev-parse --symbolic-full-name HEAD

  $ git symbolic-ref HEAD
  fatal: ref HEAD is not a symbolic ref

  $ git branch
  * (HEAD detached at 3e2ebf9)
