Er, I think my quoting was unclear. I meant the two features he
mentioned (not loading the whole file in memory, and accepting commands
from a redirected input file) applied.

Of course, AIUI ed had always _also_ been used for scripts. But I never
meant to imply that it wasn't used as an interactive editor, at least
before vi came around.
