Autocomplete using net.Conn

[vl-axentia]

Im trying to use this to get autocomplete through a socket connection, something like this:

var completer = readline.NewPrefixCompleter(
	readline.PcItem("version"),
)

func (c *Console) consoleHandler(conn net.Conn) {
	defer conn.Close()

	rl, err := readline.NewEx(&readline.Config{
		Prompt:         "> ",
		AutoComplete:   completer,
		Stdin:          conn,
		Stdout:         conn,
		Stderr:         conn,
		UniqueEditLine: true,
	})
	if err != nil {
		log.Printf("ERROR: Failed to setup readline: %+v", err)
		return
	}
	defer rl.Close()

	for {
		line, err := rl.Readline()
		if err != nil {
			break
		}

		c.executeCommand(strings.TrimSpace(line), rl)
	}
}

func (c *Console) executeCommand(cmd string, r io.Writer) {
	switch cmd {
	case "version":
		fmt.Fprintf(r, "%s\n", config.Version)
	default:
		fmt.Fprintf(r, "unknown command\n")
	}
}

If I remove the three lines redirecting stdin/stdout/stderr to the conn object, things work like I would expect when pressing TAB. However, when using conn, it instead seems to autocomplete when pressing TAB without displaying it and instead simply adds a TAB character. The second time I wrote version, I pressed TAB before pressing enter.
