Completer fault

[michalpristas]

Hi I noticed a malfunction when having PcItems with same prefix
Using this completer:

var completer = readline.NewPrefixCompleter(
        readline.PcItem("simple",
            readline.PcItem("rule",
                readline.PcItem("-name"),
                readline.PcItem("-name2"),
                readline.PcItem("-name23"),
            ),
        ),
    )

A will get following completion tree
.simple
......rule
............-name (as it is common prefix for all)
..................-name-name (this is not so good)
..................-name2
..................-name23

I would look at it on my own but I'm not sure where to look.
it works fine for
var completer = readline.NewPrefixCompleter(
readline.PcItem("simple",
readline.PcItem("rule",
readline.PcItem("-abc"),
readline.PcItem("-def"),
readline.PcItem("-qwe"),
),
),
)

prefix of agrs is not common

I think it may cause by PrefixCompleter. I will check it later :)
