Windows OS, go 1.7.4

cfg := tail.Config{ReOpen: true, MustExist: false, Follow: true}
t, err := tail.TailFile("D:\log\hotelprice\server\hotelprice_log4.log", cfg)
if err != nil {
fmt.Println(err)
}
for line := range t.Lines {
fmt.Println(line.Text)
}

the hotelprice_log4.log file is not exist.

1. create the file hotelprice_log4.log
2. open the file, then write contents, close it
   but the program can't print the contents
