Ah, that would make sense.  Some further digging in the source
history suggests that ed(1) v1.4 and prior recognized "restricted"
based on argv[0] while v1.5 changed to using the shell-script and a
"-r" parameter.  Debian is still using the symlink method which
matches what you describe.  I've filed a bug with Debian[1] to have
them use the red shell-script instead of using a symlink.

Thanks,
