There are "detached from" and "detached at" messages.  Their use was
somewhat inconsistent in the older version of Git, but at least
since 2.4.0 (quoting from Documentation/RelNotes/2.4.0.txt):

 * The phrasing "git branch" uses to describe a detached HEAD has been
   updated to agree with the phrasing used by "git status":

    - When HEAD is at the same commit as when it was originally
      detached, they now both show "detached at <commit object name>".

    - When HEAD has moved since it was originally detached, they now
      both show "detached from <commit object name>".

   Previously, "git branch" always used "from".

"git branch" and "git status" should be using the same language to
describe the situation.
