Title: JSHint-based cleanup

I started finding more "functional-yet-ambiguous" JS errors in beautify.js (thanks for being so responsive to my inline comments!), so I figured I'd wrap them all in a pull request for simplicity's sake.

For the most part, these are idempotent changes that simply fulfill the contract espoused in the existing `/*jshint */` instructions.

To verify these fixes, you'll need to have `jshint` installed:
```sh
$ npm -g install jshint
$ jshint beautify.js
```
