[issue10019] json.dumps with indent = 0 not adding newlines

[David Janes]

New submission from David Janes <davidjanes at davidjanes.com>:

In Python 2.6.4, json.dumps(...,indent=0) produced newlines as documented here: http://docs.python.org/library/json.html#json.dump
In Python 2.7, it no longer adds newlines.

'{\n"3": 1, \n"4": 2\n}'
>>> print json.dumps({3:1,4:2},indent=0)
{
"3": 1, 
"4": 2
}
