Chaining example indentation

[benatkin]

First take all the time you want with this one, as it's just documentation aesthetics.

Is this the intended indentation? From the chaining documentation:

_.chain(lyrics)
  .map(function(line) { return line.words.split(' '); })
  .flatten()
  .reduce(function(counts, word) {
    counts[word] = (counts[word] || 0) + 1;
    return counts;
}, {}).value();

It outdents 4 after the body of the anonymous function that gets passed to .reduce. It would seem that it should be outdented by 2. This would make indentation code folders fold it properly.

_.chain(lyrics)
  .map(function(line) { return line.words.split(' '); })
  .flatten()
  .reduce(function(counts, word) {
    counts[word] = (counts[word] || 0) + 1;
    return counts;
  }, {}).value();

Fixed above. Thanks for pointing it out @benatkin!

Thanks! I didn't think of your other readability improvement: moving .value() to its own line, but that's a good one. More justification for my preference of pointing things out rather than making trivial pull requests. :)
