When I run this program...

package main

import (
    "github.com/mitchellh/cli"
    "os"
)

func main() {
    ui := cli.BasicUi{os.Stdin, os.Stdout}
    ui.Ask(" >")
}

and press "tab" it seems to jump to the right 8 spaces, but pressing backspace causes it to delete only one of those spaces.

Additionally, if I type "asdf" and then press "tab" twice, pressing backspace several times will delete the tabs, the "Ask" prompt message (" >", in my case), but leave the "asdf" in its place. There seems to be a lot of abhorrent behavior around this.

I use terminator from the default repos in Ubuntu 10.04.
