OK, enough is enough. So many people persist in the practice of editing

this file, even years after the rc.conf / rc.conf.local split happened.
One way to improve upon this is to put a big fat comment at the top of
the file.  (Other ways to improve this is by renaming files, but that
will just create more confusion).
