So the issue is bugs in pre-7.0 versions of readline? That cause redisplay
issues with `complex' prompts?

The original idea was that setting show-mode-in-prompt would cause a fixed
string (that happened to be a single character) to be displayed at the
beginning of the prompt. If that variable wasn't set, they wouldn't be
displayed. Making the prompt strings user-settable didn't change that.
