raw string literals would make quoted_string example clearer

[LegalizeAdulthood]

parser/test/parser_quoted_string.cpp

Line 327 in 5788fb6

bp::parse("\"some \\\"text\\\"\"", bp::quoted_string, bp::ws);

instead of

"\"some \\\"text\\\"\""

use

R"text("some \"text\"")text"

then the backslashes intended for the parser are clear instead of doubling up all the backslashes for C++ string quoting.

Good call. Done.
