`polyglot` gives me a blank documentation

I have the following configuration in my `gulpfile.js`:

```
gulp.task("docs", function() {
gulp.src("src/**/*.js")
.pipe(documentation('html', { shallow: true }, {
name: pkg.name,
version: pkg.version
}))
.pipe(gulp.dest("dist/docs"));
});
```

When I add `polyglot: true` after the `shallow: true`, the generated documentation becomes blank. I do not want the JavaScript to be analyzed.

One particular reason is that overloaded functions have a lot of `argN: any` at the end if you leave it out in the documentation.
