fmt on json does not identify keys that are keywords

[jschnare]

If you run jsonnet fmt on something like this:

{
  "assert": null,
  "error": null,
  "function": null,
  "import": null
}

The output is invalid jsonnet:

{
  assert: null,
  error: null,
  function: null,
  import: null,
}

It should probably either error or quote any key that matches a defined keyword.

I'd like to mention, though, that otherwise it's much much better than my hacky json/jsonnet conversion scripts :-)

Thanks for the report, it was an easy fix :)
