["+", {".People[]":"Carla"}]
["-", {".State":"MA"}]
["+", {".State":"ElseWhere"}]

jq -s -c 'map( .[1] |= ((to_entries|(map(.key, .value)))  )|flatten(1) ) |.[]'

["+",".People[]","Carla"]
["-",".State","MA"]
["+",".State","ElseWhere"]

jq -s -c -r 'map( (.[1]|sub("^\\.";"")) + ("") + (" "*(15 - (.[1]|length)))+ "" + .[0] + " " + .[2]) |.[]'

People[]      + Carla
