title: Turn off line wrapping when running git grep
body: <p>Sometimes I do a <code>git grep</code>, and there's that one line which is so long it takes up half a page or more because of line wrapping. How can I tell <code>git grep</code> to turn of line wrapping, instead requiring me to scroll to the right if I want to see the rest of a long line?</p>
  
  <p>I'm using Terminal on OSX, if that's relevant. <a href="https://git-scm.com/docs/git-grep" rel="nofollow">https://git-scm.com/docs/git-grep</a> didn't indicate which program the <code>git grep</code> command  outputs to, if any.</p>
