title: How to turn off Vim relativenumber setting?
body: <p>Today I have discovered vim's <code>relativenumber</code> option. I really would like to use it, but sometimes I need to swap between relative numbering and classic one.</p>

  <p>I have tried to turn it off with <code>:set relativenumber=off</code> option (which returns me error attached above) and using <code>:set number</code> again but none of those works.</p>
