Yeah, for a file I get echo on both macOS and Linux, but not on Windows.

I think the most useful behavior for --slave is no echo at all, maybe?
But I might be missing the motivation behind --slave.

Another thing is that windows does not have --interactive. Is there a
way to run R
1) without echoing stdin, and
2) without quitting on the first error,
on all platforms?
