Fix up some failures from #21633 and #21733 (#21741)

[trivial, not reviewed]

This fixes a few futures that I must've missed in my last paratest run
(prior to paratest running futures by default!) as well as an obvious
problem with the test of the bash autocompletion which I'm not sure how
it slipped past me.

It also fixes an issue from Ben McDonald's #21733 which I happened to
notice since he's likely out for the evening.

While here, I noticed that an erroneous condition that I'd noted earlier
in #21652 has been resolved, probably by #21614 as Michael predicted, so
I added a compopts line to lock that behavior in (and removed another
that, in retrospect, felt overly paranoid).
