Subject: Never give two headings the same anchor

A repeat's count was keyed on the bare text, so a heading whose text
already ended in that count took the same anchor, as "Twice 1" did
after two of "Twice", and "About 1" after "About". A link to either
then landed on the first. The count now goes on up past any anchor
already handed out, the way GitHub's slugger does.
