Even though I think the fight is a bit futile, it is considered best practice to have newlines at the end of all files. At the request of meteor/meteor#7786, this commit adds newlines to the end of the new app skeleton `.gitignore` file. These skel files are used when generating new meteor apps so this avoids perpetuation of this problem into futrue generations. ;)
In an effort to beef up this PR, I also took the liberty of fixing the few other Meteor files which were lacking newlines (all `.gitignore` files)
