Man pages are good for finding something if you know what you're
looking for.  I never thought there would be an "unset" command, so I
would have needed to read the entire man "page" (68 pages in the case
of bash), which is rather inefficient.  I *did* scan it, but I thought
it would be quicker to ask.  It was.
