'Allow newlines' option

[cohix]

jsesc should have an option to allow newline characters:

var escaped = jsesc(string, {newlinesAllowed: true} );

So if the string contains a newline character (\n), it would not be replaced by \\n

What’s your use case exactly?

[cohix]

I have a field in my database that I want to allow real newline characters.

For now this can be solved with:

var escaped = string.split('\n').map(function(line) {
  return jsesc(line);
}).join('\n');

I’m worried that this is not common enough to extend the API for. Also, allowNewlines seems like too specific an option. If we decide to add something like this, maybe add a whitelist property instead?

Yeah I like the whitelist idea. Good call.
