what happens when you have a nested comma?
example:
{
"variables": {
"changes": "CMD [\"/bar\"],ENTRYPOINT [\"/foo\",\"--\"]"
},
"builders": [
{
"type": "docker",
"image": "ubuntu:16.04",
"run_command": ["-d", "{{.Image}}"],
"changes": "{{ user `changes`}}",
"commit": true
}
],
"post-processors": [
[
{
"type": "docker-tag",
"repository": "my/ubuntu",
"tag": "16.04"
}
]
]
}
