(cherry picked from commit 544c038)
Correct the handling of escape sequences in string literals. Don't replace escape sequences in regex expressions, for example, \r or \n. In the parser, these sequences start with \\. Same for \s, don't replace it with a whitespace, since this is also a part of a regex. Handle \\ to avoid that the sequence is escaped and returned as \\\\. (cherry picked from commit d266e80)
