Semi-automatic update. These checks were done:
- built on NixOS
- ran `/nix/store/pdxydl7lg0pbpcmh2332yygbb7b4vbq2-jshon-20160111.2/bin/jshon help` got 0 exit code
- found 20160111.2 in filename of file in /nix/store/pdxydl7lg0pbpcmh2332yygbb7b4vbq2-jshon-20160111.2
This fixes a somewhat critical (security?) bug.
We are trying to get it merged upstream but have had no response from
the ordinary maintainer in over a week.
(See <https://github.com/keenerd/jshon/issues/53>.)
