net/textproto: fails to trim header value

[Dmitry Vyukov]

The following program:

package main

import (
    "bufio"
    "bytes"
    "fmt"
    "net/http"
)

func main() {
    data := []byte("GET / HTTP/0.0\nh:\n 0 \n\n")
    r, err := http.ReadRequest(bufio.NewReader(bytes.NewReader(data)))
    if err != nil {
        return
    }
    fmt.Printf("%q\n", r.Header.Get("h"))
}

prints:

"0 "

Header values must be trimmed.
