Thanks, but I'd prefer a less obscure way of telling whether this
is going into *Help* buffers.  Is this really the only way?  Or maybe
the mouse-face etc. should not be put as part of
substitute-command-keys, but by the Help mode itself, when the text is
already in the *Help* buffer?  As we use substitute-command-keys more
and more, these problems will probably pop up more and more, so maybe
we should rethink whether this part is really something it should do.
