[feature idea] option to inline arrays regardless of length.

[Steve Shaw]

When viewing a large json, such as geojson, it would be very handy to be able to have an alternative to "inline short arrays", that inlines "leaf" arrays regardless of length, to specified depth.

The result would be part-way between "minification" and the traditional fully-expanded pretty-printing of json.
In the case of geojson, a level of "2" would collapse all "coordinates" members, making the file much easier to view.
