+18.8 Consider convenience options for JSON and XML?
+
+ Could we add `--xml` or `--json` to add headers needed to call rest API:
+
+ `--xml` adds -H 'Content-Type: application/xml' -H "Accept: application/xml" and
+ `--json` adds -H 'Content-Type: application/json' -H "Accept: application/json"
+
+ Setting Content-Type when doing a GET or any other method without a body
+ would be a bit strange I think - so maybe only add CT for requests with body?
+ Maybe plain `--xml` and ` --json` are a bit too brief and generic. Maybe
+ `--http-json` etc?
