jsonencode pretty-printing option #15
Description
The normal jsonencode behavior just sticks all the JSON in one big long single-line string. This is fine for machine-readability and efficiency, but hard for humans to read and edit, so it's not suitable for stuff like config files. Add a pretty-printing option to jsonencode().
Matlab does not support this, so this would be an Octave extension.
This is somewhat in conflict with the goal to optimize jsonencode by pushing it down to C++, because this will be more difficult to write in C++ than in M-code.
