Pressing return at "Display all ... possibilities" completion question propagates internal error up to Prompt(...)

[frou]

$ go run allcomp.go 
> [Tab] [Tab]
Display all 101 possibilities? (y or n) [Return]
2016/01/13 19:57:22  liner: internal error
$ 

I'd expect it to either keep waiting for a y/n press (like it does if you press m for maybe) or take Return to mean the affirmative?

package main

import (
    "strings"
    "log"
    "github.com/peterh/liner"
)

var (
    names = []string{
        "xxxxx", "a1", "a2", "a3", "a4", "a5", "a6", "a7", "a8", "a9", "a10",
        "a11", "a12", "a13", "a14", "a15", "a16", "a17", "a18", "a19", "a20",
        "a21", "a22", "a23", "a24", "a25", "a26", "a27", "a28", "a29", "a30",
        "a31", "a32", "a33", "a34", "a35", "a36", "a37", "a38", "a39", "a40",
        "a41", "a42", "a43", "a44", "a45", "a46", "a47", "a48", "a49", "a50",
        "a51", "a52", "a53", "a54", "a55", "a56", "a57", "a58", "a59", "a60",
        "a61", "a62", "a63", "a64", "a65", "a66", "a67", "a68", "a69", "a70",
        "a71", "a72", "a73", "a74", "a75", "a76", "a77", "a78", "a79", "a80",
        "a81", "a82", "a83", "a84", "a85", "a86", "a87", "a88", "a89", "a90",
        "a91", "a92", "a93", "a94", "a95", "a96", "a97", "a98", "a99", "a100"}
)

func main() {
    line := liner.NewLiner()
    defer line.Close()
    line.SetTabCompletionStyle(liner.TabPrints)
    line.SetCompleter(func(line string) (c []string) {
        for _, n := range names {
            if strings.HasPrefix(n, strings.ToLower(line)) {
                c = append(c, n)
            }
        }
        return
    })
    log.Println(line.Prompt("> "))
}
