File	Description
scanner/scanner.go	Handle \r in scanDoubleQuote, skip following \n in CRLF pairs
decode_test.go	Add tests for multi-line continuations with LF, CRLF, and lone CR

[Copilot]

Off-by-one check: when at a '\r' at src[idx], the '\n' to skip is at src[idx+1], not src[idx+2]. Update the condition to if idx+1 < size && src[idx+1] == '\n'.

Suggested change

	if idx+2 < size && src[idx+2] == '\n' {
	if idx+1 < size && src[idx+1] == '\n' {

[shuheiktgw]

This is not true. We have to check src[idx+2].

• src[idx] = \
• src[idx+1] = \r
• src[idx+2] = \n
