Well, I found a slightly different approach that worked, making the test into a 
normal shell "if test x$THISVAR = x" test as a "normal" rule action, and this 
satisfied my need.

Maybe next time I'll try adding a space and see how it "works". :)

Tom,

I can't disagree with your portability goal, and I was able to find a perfectly 
acceptable solution to my problem, so I won't be asking you to work on it.

Thanks for the advice and honest reply.
