title: How to use Vim 7.4 on Mac OS after install it by brew?
body: <p>I have installed vim by brew on the newest Mac OS:</p>
  
  <pre><code>brew install vim
  </code></pre>
  
  <p>And when I type <code>brew info vim</code>, it shows:</p>
  
  <pre><code>vim: stable 7.4.891, HEAD
  Vi "workalike" with many additional features
  http://www.vim.org/
  Conflicts with: ex-vi

    Built from source
  From: https://github.com/Homebrew/homebrew/blob/master/Library/Formula/vim.rb
  ...
  </code></pre>
  
  <p>But if type <code>vim</code>, it shows me a <code>7.3</code> version's vim:</p>
  
  <pre><code>VIM - Vi IMproved
    version 7.3
  ...
  </code></pre>
  
  <p>How can I use the <code>7.4</code> version?</p>
