This wording is copied-and-pasted from the other similar tests.  I agree
that it's advocating a solution that might be overkill, but if we change
it we should also change the existing messages.  I don't mind doing
that in HEAD; less sure about the back branches, as (I think) these
are translatable strings.

Thoughts?
