Personally, I'd object to introducing a hard dependency on Expect, as
there are no doubt a lot of developers and buildfarm members who don't
have that installed. But I see no reason we couldn't skip some tests
if it's lacking, as we're already doing with IO::Pty in
010_tab_completion.pl.

That does raise the question of whether Expect makes things enough
easier than raw IO::Pty that it's worth adding that dependency (and
hence foregoing the tests on some machines). But I'm prepared to be
convinced on that point.
