Bare CR are recognized as newlines at least for the multi-line comments starting from ethereum/solidity@f85f6ba#diff-16d471fed3639e7154b8661355cf66d41efe54a05f2d8e67017b9a301d19f7cd, so I'm happy to merge this.

It seems that solc also respects these for line breaking the strings/single line (doc) comments:

bool Scanner::isUnicodeLinebreak()
{
	if (0x0a <= m_char && m_char <= 0x0d)
		// line feed, vertical tab, form feed, carriage return
		return true;
	if (!m_source.isPastEndOfInput(1) && uint8_t(m_source.get(0)) == 0xc2 && uint8_t(m_source.get(1)) == 0x85)
		// NEL - U+0085, C2 85 in utf8
		return true;
	if (!m_source.isPastEndOfInput(2) && uint8_t(m_source.get(0)) == 0xe2 && uint8_t(m_source.get(1)) == 0x80 && (
		uint8_t(m_source.get(2)) == 0xa8 || uint8_t(m_source.get(2)) == 0xa9
	))
		// LS - U+2028, E2 80 A8  in utf8
		// PS - U+2029, E2 80 A9  in utf8
		return true;
	return false;
}
