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”

p RUBY_DESCRIPTION
p Readline::VERSION
p Readline.completion_append_character
Readline.completion_proc = ->(input){[input]}
IO.pipe do |r, w|
Readline.output = (w << “Readline\t”).reopen("/dev/null")
Readline.input = r
Readline.completion_append_character = nil
p Readline.completion_append_character
p Readline.readline
p Readline.completion_append_character

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.

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.
