The `dependency' on show-mode-in-prompt is intentional: the strings aren't
prefixed to the displayed prompt string unless that variable is enabled.
That has been the case even when the strings weren't user-settable (e.g.,
bash-4.3). If the documentation doesn't make that clear, then I need to
clarify it.
