Sweep the entire documentation again. Last done in commit209e64d9ed(qapi: Refill doc comments to conform to current conventions). To check the generated documentation does not change, I compared the generated HTML before and after this commit with "wdiff -3". Finds no differences. Comparing with diff is not useful, as the reflown paragraphs are visible there.
