Hmm... the non-MacOS ed documentation seem fairly clear that prompting
is off by default and when it's on it's a "*" (unless there's an error).

Anyway, ignoring output turned out to be harder than expected ---
finding a consistent point in the code that didn't give blank
lines (that I couldn't necessarily rely on being present) wasn't that
easy. I'd probably have needed to edit the output to compare only
relevant lines.

With a bit of luck, dc is easier to manage all round.
