I'm sorry I forgot to mention that, it was mainly meant as a way to show
that this is easily possible (i.e. that the formatting is decoupled from
the logic, so that additional and different formats can be added without
influencing the printing logic). It'd be easy to split this up. What
kind of documentation should I include? 
The test suite should work fine, *if* it compares EXPECTED and OUTPUT
not character-by-character, but rather by pretty-printing both the
expected and the actual outputs by some JSON pretty-printer (like python
-mjson.tool). I can of course provide additional test-cases for
--format=sexp.

How should I proceed on this? Re-submit the patch with the sexp-support
removed and only JSON updated?

Thanks!
