Please follow the established conventions for code formatting... spaces after arguments and before curly braces, e.g.

    fs.readFile(filePath, 'utf8', function(err, data) {

Also (see lines below) early bailout `if (err) return callback()` statements are OK but should be on one line, all other conditions (even one-liners) should have braces and be multi-line.

There's a link to the style guide that we (mostly) follow in the [readme](https://github.com/JedWatson/keystone#contributing)

(don't mean to sound ungrateful - I really appreciate your work - just want to keep the coding conventions in check)
