Description:
This function (MarshalIndent) can be used to achieve JSON "pretty-printing". 
I ended up asking on stackoverflow.com
(http://stackoverflow.com/questions/19038598/golang-pretty-print-json) in order to find
this method because I was thinking I'd find it from that keyword ("pretty
print").  Suggest adding the following text: 

This function provides the equivalent of JSON "pretty-printing".  Example:

b, _ := json.MarshalIndent(m, "", "    ")

I guess we could say "pretty print" somewhere.

We don't need to list such obvious uses for things.
