Oops, I meant comm, not comp. My brain is still a bit fuzzy. :)
I haven't used parentheses like that. I usually use backticks, but this 
might actually be clearer. More for me to learn. Thanks for that.
Much more concise that my complicated uniq stuff, but has the problems 
arising out of sort throwing away context (which I didn't mention until 
later, sorry).

Thanks Little Girl,
