Oh, then I don't understand why you separated that sentence into its own

paragraphs should go before the ChangeLog entries, because that format
doesn't allow for multiple paragraphs in the same entry (AFAIK)).

There should be double space between sentences though.

Oops, right.  (I would consider just putting a single save-excursion
around the 'when', but it doesn't hugely matter either way (and Drew
would probably not like the single save-excursion version ;) [1]).)
