Oops.  I blew it.  Working on GNU awk seems to have permanently damaged my
brain (there are a couple of differences between "real" awk and GNU awk which
I couldn't convince the author were worth changing, specifically in 'exit'
(not next); GNU exit actually does what I thought next would do, instead of
exiting entirely).
