Isn't the rule these days "HEAD must be either detached or point
into refs/heads/"?  I thought "checkout" ensures that, and I am
tempted to think that "symbolic-ref" that works on HEAD should be
consistent with "checkout".  So "make sure HEAD is within refs/"
would certainly be "not wrong per-se" but not sufficiently tight,
I suspect.
