Unexpected behaviour with incorrect input

[haanjde]

Describe the bug
Given the input, which is apparently is wrong, I would have expected an error message.

To Reproduce

$ echo '{ "atribute1": { "attribute2": "name1", "attribute3": { "attribute2": "name2" }, "attribute3": { "attribute2": "name3" }, "attribute3": { "attribute2": "name4" } } }' | jshon '.'
{
  "atribute1": {
    "attribute2": "name1",
    "attribute3": {
      "attribute2": "name4"
    }
  }
}

Expected behavior

$ cat expected_output.json 
{ 
 "atribute1": {
  "attribute2": "name1",
  "attribute3": {
   "attribute2": "name2"
  },
  "attribute3": {
   "attribute2": "name3"
  },
  "attribute3": {
   "attribute2": "name4"
  }
 }
}
$

Environment (please complete the following information):

• OS and Version: Linux Ubuntu 18.04.2
• jshon version:

$ jshon --version
20130901

Additional context
I suspect this to be a language problem, as the competition (jq) does the same. An error message would be nice, though.
