Pretty format for variable declarations

Project standards demand the equal signs must be aligned for better readability.

Input

var parser = require('../src/grammar.js'),
    src = require('../src/blueberry.js'),
    fs = require('fs'),
    glob = require('glob');

Output

var parser = require('../src/grammar.js'),
    src    = require('../src/blueberry.js'),
    fs     = require('fs'),
    glob   = require('glob');
