-- Converts any iteration marks (々 and 〻) into the relevant characters in the text, where n repeated iteration marks repeats n previous characters (e.g. "時々" = "時時", "馬鹿々々しい" = "馬鹿馬鹿しい" etc). Punctuation and unconnected sets of iteraton marks block iteration, with excess marks being left as-is. For example, "X,Y々々" = "X,YY々", and "X々Y々々" = "XXYY々" (not "XXYXY").
