you want an ed with a cursor, you need only take GNU ed and hook it up
with GNU readline, and there you go.
That would allow me to edit the command I'm entering, e.g. `,n'. What
I'm suggesting is the command I'm entering can manipulate the in-line
cursor when I press Enter to submit the command. I don't want
interactive editing of lines in the file; I know where to find that.
I don't think I understand what you're getting at. It's been decades,
I think, since I last saw / used open mode, which is what I thought
you wanted, so I think I'm confused.
I think what Ralph wants is something like "LINES=1 vi"
but without clearing the screen so that commands that
are cursor relative can work. rlwrap and readline don't
edit the current line in the file, only the command input.
