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.

ed 1.14.2-1 here hasn't.  And I wouldn't expect its dependencies to
grow.

    $ ldd /bin/ed
            linux-vdso.so.1 (0x00007fff215d4000)
            libc.so.6 => /usr/lib/libc.so.6 (0x00007fd89767a000)
            /lib64/ld-linux-x86-64.so.2 => /usr/lib64/ld-linux-x86-64.so.2 (0x00007fd897a31000)
    $
