Yes.  My typo made it look as if I meant to say '@' was a bad
choice, but we are in agreement that '@' is better than any other
random choice of single punctuation letter.

It is just the "strip this, strip that" explanation, which is not
technically correct, does _not_ have to be our justification for
picking '@' as a short-hand for HEAD.
