Ah, you're right on both counts. It's not the `=` in the file name 
that's the issue, it's that I should have done:

   printf ... | awk 'script' -

(with `-` on the end) so that I started populating ARGV[] at ARGV[2] 
instead of ARGV[1] since ARGV[1] was already consumed when the `NR==FNR` 
block was being interpreted.

Thanks,
