Bug#888112: diffoscope: compare JSON files using Python jsondiff module

[Paul Wise]

Package: diffoscope
Version: 90
Severity: wishlist

The Python jsondiff module allows comparing JSON files in a better way
than just comparing the plain text like diffoscope currently does.

The jsondiff command-line program outputs only the JSON attributes that
are different between the files, but the Python module probably allows
more advanced analyses.

If jsondiff doesn't prove useful or is hard to use, please pretty-print 
JSON files by loading the JSON file into a Python object and call
json.dump() with the indent=4 parameter and then diff the text.
