cpphash.c (collect_expansion, [...]): Make the escape character in macro buffers '\r', not '@'.

	* cpphash.c (collect_expansion, macroexpand,
	push_macro_expansion): Make the escape character in macro
	buffers '\r', not '@'.  Remove code to protect literal
	occurences of the escape character; '\r' cannot appear
	in a macro buffer unless we put it there.
	* cpplib.c (skip_comment, copy_comment, cpp_skip_hspace,
	copy_rest_of_line, cpp_get_token, parse_string,
	parse_assertion): '\r' might be a backslash-newline marker, or
	it might be a macro escape marker, depending on
	CPP_BUFFER (pfile)->has_escapes.  '@' is not a special
	character.
	* cpplib.h: Update commentary.
