I think you can lose the check on p[1]: whenever there's an opening token, we can just skip all whitespace, including the initial newline.
JSON allows un-escaped '{' '[' inside a string:
$ jq <<< '{"blah":"[{"}' { "blah": "[{" }
And even if it were escaped it's escaped with the traditional backslash sequence e.g. '\"', thus the very easy state machine above would still consider it.
TBH I didn't check if it's present in our data though.
I hadn't considered that scenario. Better to be safe and keep the additional check then. -- Andrea Bolognani / Red Hat / Virtualization
