Yes, I do! I was concerned that users were falling into a common
error, where they forget to wrap variable references in $(); so,
if it looks like an expr has arithmetic operators, but no variable
refs, then you get this message.

Yes, I *could* have made it more intelligent. File a bug, and I'll
see if I can do so. At the worst, you can ignore this warning, or
I can simply remove this overly-simple warning.
