title: Sublime Text MySQL Build System variable substitution issue
body: <p>I'm trying to configure Sublime text to do MySQL build, following is the script:</p>
  
  <pre><code>{
      "cmd": ["mysql", "--default-character-set=utf8", "-uuser", "-ppwd", "-hlocalhost", "-v", "db_mine", "-e source main.sql"],
      "selector": "source.sql"
  }
  </code></pre>
  
  <p>As it is, it works for file <code>main.sql</code>, as presented in the script. Obviously that should be changed, I see people using $file there.</p>
  
  <p>The problem is that here (Windows 7) it's not working.</p>
  
  <p>If I change it to <code>$file</code>, then I get:</p>
  
  <pre><code>ERROR at line 1: Unknown command '\U'.
  </code></pre>
  
  <p>Any suggestion?</p>
