Feature Request: Ensure single newline ending when prettify on save is enabled

[bradoyler]

One annoyance I have is that when saving json files it removes the newline ending. Would it be ok to turn off the removal of newline on save?

Ugh, I also hate when files don't end with a newline. Yuck, even having Atom's whitespace package installed, enabled, and configured to enable Ensure Single Trailing Newline doesn't help.

I can't work on this right this minute but I'll try to fix it soon. Thanks for the ticket!

Ideally this could come from a .editorconfig file... along with indent size / style and newline style,

@jnields there's at least one (maybe more) editorconfig packages for Atom that should, in theory, make this work. Those packages would set Ensure Single Trailing Newline properly, and then the pretty-json package should correctly honor that setting.
