Function JoinRootPath

fs/fspath/path.go:330–356

JoinRootPath joins filePath onto remote If the remote has a leading "//" this is preserved to allow Windows network paths to be used as remotes. If filePath is empty then remote will be returned. If the path contains \ these will be converted to / on Windows.
