title: How do I get Vim to highlight YAML mapping key when it contains a space?
body: <p>I'm using Vim 7.3 on Ubuntu linux.</p>
  <p>When I'm editing a YAML file</p>
  <pre><code>This:
      fnordy fnord: fnord
      fnords: super fnord
  </code></pre>
  <p>&quot;fnords&quot; would be colorized, but &quot;fnordy fnords&quot; would not be.</p>

  <p><img src="https://i.stack.imgur.com/Not3Z.jpg" alt="fnordy fnord then fnord" /></p>
  <p>How can I fix this? I'm looking at my <code>/usr/share/vim/vim73/syntax/yaml.vim</code> file, but I don't understand it enough to fix this.</p>
  <h2>UPDATE</h2>
  <pre><code>:color 
  slate
  
  :echo &amp;ft
  yaml
  </code></pre>
  <p>On <code>fnord: fnordy</code> (at the beginning of the line): yamlBlockMappingKey</p>
  <p>On <code>fnordy fnord: fnord</code> (at the beginning of the line): yamlPlainScalar</p>
