mail.Address.String() does not take care of non-ASCII name with comma

[cention-sany]

1. go version 1.4.2
2. Linux sanydellubuntu 3.19.0-30-generic log_test fails because of ??? filename #33-Ubuntu SMP Mon Sep 21 20:58:04 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux
3. See my code below.
4. I expected mail.Address.String() can escape the comma for non-ASCII characters.
5. Comma is output without escape and cause error mail: no angle-addr during parsing.

package main

import (
    "log"
    "net/mail"
)

func formatEmailAddress(emailaddress, name string) string {
    a := new(mail.Address)
    if "" == emailaddress {
        return ""
    }
    a.Address = emailaddress
    if "" != name {
        a.Name = name
    }
    return a.String()
}

func main() {
    s := formatEmailAddress("[email protected]", "naé, mée")
    log.Println(s)
    a, err := mail.ParseAddress(s)
    if nil != err {
        log.Println("error because:", err)
    } else {
        log.Println("name is:", a.Name, "email is:", a.Address)
    }
}

This is a duplicate of #11292. I will fix that bug when CL 14957 is merged.
