I don't understand what's going on here.

In this test case, we use an invalid UTF-8 sequence in a JSON string
literal (json_in). So "/* invalid */" could be justified; perhaps it's
just too laconic.
The "/* bug: not corrected */" comment seems indeed wrong, "json_in" is
*input*, there's nothing to correct on it.

When the JSON parser rejects the invalid sequence, it's actually
correct. So why the "bug" comment? Are we expecting (according to the
comment in utf8_string()) U+FFFD?

In this test we're trying to format a UTF-8 byte sequence (utf8_in) as a
JSON string. The source is invalid. The JSON formatter should either
reject it, or emit an U+FFFD in its place. The actual JSON output is
probably wrong, hence the "bug" part is OK, but I thought what we
expected is not U+FFFF but U+FFFD. Hence that part of the comment is
wrong. ... Hm, OK the leading comment has some notes on this as well.
So what your patch does here is:
- remove the halfway OK comment "/* invalid */" -- I think it wasn't
really wrong, but I won't miss it,
- removes an in fact bogus comment,
- (removes a runaway comma).
My eyes are bleeding.
