I think you've misunderstood the help text. Try ...

        edit editor "emacs %s"

This syntax corresponds to "edit FIELD VALUE" as described when "help edit" is 
entered.

Did you install a command line version of emacs or a GUI version?

I don't use emacs, but do use mvim (GUI version of vim).  For mvim to function 
correctly, I added the following to my ~/.octaverc file.

        edit editor "mvim %s"
        edit mode async

I haven't used a GUI version of emacs, but you may need to set "mode" so 
"async" as well.
