I've now made the change, but I haven't totally replicated the look of
`C-h b' and the like.  It used to have

  ... stuff ...

  ... more stuff ...

With the change, it now says:
  ... stuff ...
  ... more stuff ...

I can add back the newlines if people want.  I'd rather get rid of the
^L characters, though.  Do they have any purpose any more?
