 いまいです。
 
 GNU readline library での話ですが、6 系のものを使うと TAB キーでの補完
 後に Readline.completion_append_character がデフォルトの " " に戻ってし
 まいます。しかも、" " 以外にセットしても、補完された単語にはデフォルト
 の " " が付加されます。
 
 
 require "readline"

 changelog に以下のように書いてあって、補完後にリセットされるのは意図的
 なようです。Ruby の readline 側で何とかならないものでしょうか？
 
 This document details the changes between this version, readline-6.0,
 and the previous version, readline-5.2.
 (snip)
 f.  Fixed a bug that caused the completion append character to not be reset to
     the default after an application-specified completion function changed it.
