Actually we can do better: we can have --where only refer to
*subsequent* --trailer options.  This will require more refactoring
(probably making a new struct that can be passed to process_trailers),
but the first two patches should be the same.

I'll have time for this only after vacation (so at the end of July), and
it's backwards-incompatible with this series.  Reviews are welcome
anyway. :)

Thanks for encouraging me.  It's always a pleasure when I can scratch my
git itches!
