So I had to work to figure out what the change was, since you didn't say
in the changelog and you refilled the paragraph.  But this looks like a
*factual* error, giving the wrong number of bits, right?  It seems like
the changelog should say that.  Do the people who know about this stuff
agree that the change is correct?
