If you have the string /usr/bin, prior to this patch it would not be quoted by our YAML serializer. But a string like C:\src would be, due to the presence of a backslash. This makes the quoting rules of basically every single file path different depending on the path syntax (posix vs. Windows). While technically not required by the YAML specification to quote forward slashes, when the behavior of paths is inconsistent it makes it difficult to portably write FileCheck lines that will work with either kind of path.
