I think this is the wrong place to put this text.  This is a user
option of no particular importance to Lisp programmers, so it should
be in the user manual, not in the ELisp manual.

I think if we change the default behavior, this entry should be
reworded to describe the changed behavior.  Like this:

  *** The "Info node" and "URL" prefixes to hyperlinks are now hidden.
  Help mode buffers no longer display these prefixes when they show
  links to Info manuals and Web pages.  Customize 'help-mode-hide-markup'
  to nil to get previous behavior.

I'd prefer a more specific name for the variable, like
help-mode-hide-info-and-url-prefix.  Yes, that's a mouthful, but if we
don't expect to many people changing that, I think it's OK.
