It says "install the functions", which means they should be evaluated
or loaded, and that tells you the Lisp code should already be
available in some Lisp buffer, whether it's *scratch* or some *.el
file.

So why did you think it speaks about the text in the Info buffer?
That's not the intent of the text, and the text says as much.

So I'm not sure we should install this fix.  Any other opinions?

In any case:

  . just talking about *scratch* is too restrictive
  . the commit log message is not according to our conventions (see
    CONTRIBUTE)

Thanks.
