Sure, but I don't think that we can reliably test the case where one
of the switches triggers a backend-side error, which is what my point
is about.  I have added a note about that, with a couple of extra
tests with -f, with both success and failure scenarios.  And we'd
better add -X to all the commands as well.  These are added only on
HEAD as the test file is rather new.

Looks fine to me, so applied down to 10.
