I'm happy to report that I have found a reasonable solution
to the problem: see [5/6].

The larger problem still persists: in my opinion, b397ea4 takes the
wrong approach to the problem it is attempting to solve; nobody cares
_how_ I got to a detached HEAD state; what is important is that I'm
stuck in such a state and need useful information.

The correct approach, in my opinion, is already taken by my prompt:
use git describe.

  artagnon|checkout-dash=$ git checkout @~1

Now compare this with the approach taken by the patch:

  artagnon|(checkout-dash~1):~/src/git$ git status
  # HEAD detached at 7aa7992
  nothing added to commit but untracked files present

Completely useless.

Unfortunately, it is too late to revert b397ea4, as too much stuff
already depends on it now (see builtin/branch.c for example).
Reworking the code to use describe is not an easy task at all:
describe has no exposed API, and is polluted with die() statements.
Nevertheless, it can be a fruitful exercise for someone who is willing
to take on the challenge.
