This is a very good thing!  (and I like to repeat it :-)

But it reminded me another problem with the *Help* buffer: it doesn't
have a final newline.  This is especially annoying when a large *Help*
buffer with a long last line is scrolled horizontally to the left when
point reaches the end of the buffer.  For example, this problem can be
observed in the *Faces* buffer (invoked by the `list-faces-display').
Adding a final newline solves this problem.
