[Feature request] Comma first

[bag-man]

It would be great if this could have an option to support comma first syntax. An example:

var target =
  { host: this.domain
  , port: this.port
  , path: '/'
  , method: 'GET'
  , agent: false
  , headers: { 'User-Agent': 'Mozilla/5.0' }
  }

We use the above formatting for objects, and ArgWrap will correctly wrap this down to one line, however when wrapping that one line back out to a multi-line object, it defaults to comma last (Example below), having an option to create the object in the above format would be amazing!

var target =
  {
    host: this.domain,
    port: this.port,
    path: '/',
    method: 'GET',
    agent: false,
    headers: { 'User-Agent': 'Mozilla/5.0' }
  }
