The infrastructure does that if you pass WARN_ONLY in the flags. (Which
loopfiles() does by default.)
Don't close stdin when they -, it makes the rest of your pipeline unhappy.
(do_lines() in lib/ checks for this)...
Actually, lemme rewrite this to use do_lines(), via the loopfiles_lines() bridge
that's already in lib. And use a dlist since that already has a function to
allocate the wrapper for us and it's trivially reversible...
There, checked in on top of yours. Try now?
