I am wondering if this behavior has recently been introduced with Evernote as I am very sure it didn't add the newline when copying from Evernote a couple of months ago.
I use Evernote for saving commands I use in Linux terminal a lot and these added newlines aren't just annoying but really dangerous. This is really a security risk for my work. Sorry, but I will have to cancel the subscription if this behavior isn't changed fast.
