Allow 'compact' code with newlines between global statements

[gfwilliams]

Quite often I see minified code that puts individual statements at the global level on different lines.

For example:

function a() { ... }
function b() { ... function c() { ... }  }
var x;

Unfortunately right now it looks like escodegen only does:

function a() { ... }function b() { ... function c() { ... }  }var x;

or adds newlines everywhere.

A semi-compact option would be great, and I've had some success doing this by adding a special newline variable that only gets added from Syntax.Program.

Is this something of interest? I can produce a PR?

Why is this useful?

In my case, I'm using escodegen to create minified code to send to a microcontroller running JS (Espruino). It interprets each function as it gets it after a newline is received - effectively as if it were entered by a user in a REPL.

If everything is in one line, you end up with several thousand characters to execute in one go, which fills up all the available memory and breaks things.
