json_lexer[] maps (lexer state, input character) to the new lexer state. The input character is consumed unless the new state is terminal and the input character doesn't belong to this token, i.e. the state transition uses look-ahead. When this is the case, input character '\0' would result in the same state transition. TERMINAL_NEEDED_LOOKAHEAD() exploits this. Except this is wrong for transitions to IN_ERROR. There, the offending input character is in fact consumed: case IN_ERROR returns. It isn't added to the JSON_ERROR token, though. Fix that by making TERMINAL_NEEDED_LOOKAHEAD() return false for transitions to IN_ERROR. There's a slight complication. json_lexer_flush() passes input character '\0' to flush an incomplete token. If this results in JSON_ERROR, we'd now add the '\0' to the token. Suppress that.
