Ah ok I thought -e basically negated the effect of -r for some reason but I
guess not (like you can still use \ to escape line continuations without -r it
seems). Long ago I assumed "read <<<str" was equivalent to "read -r <<<$'str'"
based upon what the manual says.

BTW I like how "show-mode-in-prompt On" together with "read -ep prompt" shows
the indicator. That's a nice touch.
