@vladikoff Very cool.

Is there a speed/perf difference between:
```javascript
'{,<%= yeoman.app %>/**/,grunttasks/**/,scripts/**/,server/**/,tests/**/}*.js',
```
and the longer/legible:

```javascript
'*.js',
'<%= yeoman.app %>/**/*.js',
'grunttasks/**/*.js',
'scripts/**/*.js',
'server/**/*.js',
'tests/**/*.js'
```
