[docs] Documentation typo in json docs

https://docs.python.org/2/library/json.html When describing how to use json.tool, you provide the following example code: $ echo '{"json":"obj"}' | python *-mjson.tool* { "json": "obj" } $ echo '{1.2:3.4}' | python *-mjson.tool* Expecting property name enclosed in double quotes: line 1 column 2 (char 1) However, there is no space between the *-m* and the *json.tool*. There should be a space in those 2 places.
