if you're set -o vi you can hit v to edit in a "proper" editor ($VISUAL?)

maybe there's an equivalent for set -o emacs ?

I didn't know about the multiline thing but surely if you're editing
something that long, a proper editor is going to be more convenient

I just noticed a somewhat odd behaviour in openbsd ksh where
if you are in vi mode and hit v and your commandline buffer is
empty, it bells and won't open the editor. Not sure I'd call it a bug
but it did surprise me
