* ext/readline/readline.c (readline_attempted_completion_function):

in Readline module with GNU Readline 6 case, Readline module
  resets completion_append_character to " ", after it executes
  completion. So, Readline module stores
  completion_append_character, and Readline module always sets it
  after Readline module executes completion. [ruby-dev:43456]
  [Feature #4635]
