I was thinking of avoiding the passive voice and writing
"foo must be greater than zero"
which removes all doubt. It's not necessary to keep the "integer"
aspect of the existing text, because if someone had supplied a
non-integer value, that would not have gotten this far anyway.

I think for consistency it'd be good to change 'em all. I'm almost
tempted to put this matter into our message style guide too.
