Of course, aside from missing "then", this needs to use the
real "sed", so this has to be

	if test -z "$must_abort"
        then
		command sed "$@"
	fi

or something like that.

An approach along this line may reduce both the false negatives and
false positives down to an acceptable level, but I doubt the result
would be efficient enough for us to tolerate the runtime penalty.
