Bug: curl JSON formatting

[Eisa01]

Currently curl does not have any type of formatting when requesting for JSON, this makes the information hard to read in CLI.
e.g.: The below is quick comparison between ipinfo.io and ifconfig.co, Please find the below for comparison purposes pasted directly from my CLI (some censoring have been applied).

curl ipinfo.io
{
  "ip": "86.**.1**.2*1",
  "hostname": "bba5***.alshamil.net.ae",
  "city": "Aj** City",
  "region": "SomeRegion",
  "country": "XX",
  "loc": "25.***,**.4**88",
  "org": "Censored",
  "timezone": "Censored",
  "readme": "https://ipinfo.io/missingauth"
}

curl ifconfig.co/json
{"ip":"86.**.1**.2*1","ip_decimal":293847892347892347,"country":"Censored","country_iso":"Censored","country_eu":false,"region_name":"SomeRegion","region_code":"Censored","city":"Aj**City","latitude":25.***,"longitude":4**88,"time_zone":"Censored","asn":"Censored","asn_org":"Censored","user_agent":{"product":"curl","version":"7.55.1","raw_value":"curl/7.55.1"}}
