[issue16333] Trailing whitespace in json dump when using indent

[Zach Mathew]

New submission from Zach Mathew:

When using the indent option in json.JSONEncoder, extra trailing whitespace (preceding the newline) is added to list and dict items.

For example:

>>> import json
>>> json.dumps(['foo', 'bar'], indent=1)
'[\n "foo", \n "bar"\n]'

Notice the blank space between "foo", and \n

EXPECTED OUTPUT:

'[\n "foo",\n "bar"\n]'
