[issue33927] Allow json.tool to have identical infile and outfile

[Michael Kuhlmann]

New submission from Michael Kuhlmann <michaelkoolman95 at gmail.com>:

It would be nice to have same infile and outfile for json.tool to replace json files with their pretty-printed version.

Currently, if I try this I get an error:
$ python3 -m json.tool example.json example.json
Expecting value: line 1 column 1 (char 0)
