MapReduce is about optimizing algorithms
not about formatting.

If you really need formatting, create a list:

function(head, req) {
  var result = {}
  while (r = getRow()) {
    result[r.key] = r.value;

This should work. However, this simple implementation is not memory savvy.
Send row one by one for better memory management.
And if you really need high performance, forget formatting.
