Retain do-block and chained .method newlines in compiled javascript

[blendmaster]

The do block and spaced dot attribute syntax make for really nice looking coco, but the compiled javascript collapses all the newlines inside a do-block or the usual jQuery chaining style method calls:

method do
  firstArgument
  secondArgument
  thirdArgument

object
  .chain stuff, ->
    method
  .chain more_stuff, with_multiple_args
  .chain even_more_stuff

currently compiles to

method(firstArgument, secondArgument, thirdArgument);
object.chain(stuff, function(){
  return method;
}).chain(more_stuff, with_multiple_args).chain(even_more_stuff);

I'd like it to compile to:

method(
  firstArgument,
  secondArgument,
  thirdArgument);

object
  .chain(stuff, function(){
    return method;
  })
  .chain(more_stuff, with_multiple_args)
  .chain(even_more_stuff);

which would make reading and debugging the resulting javascript easier, especially for methods with lots of arguments or complicated expressions as arguments.
